Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: Unregister clocks/resets when unbinding
Currently, unbinding a CCU driver unmaps the device's MMIO region, while
leaving its clocks/resets and their providers registered. This can cause
a page fault later when some clock operation tries to perform MMIO. Fix
this by separating the CCU initialization from the memory allocation,
and then using a devres callback to unregister the clocks and resets.
This also fixes a memory leak of the `struct ccu_reset`, and uses the
correct owner (the specific platform driver) for the clocks and resets.
Early OF clock providers are never unregistered, and limited error
handling is possible, so they are mostly unchanged. The error reporting
is made more consistent by moving the message inside of_sunxi_ccu_probe.(CVE-2021-47205)
In the Linux kernel, the following vulnerability has been resolved:
thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR
In some case, the GDDV returns a package with a buffer which has
zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10).
Then the data_vault_read() got NULL point dereference problem when
accessing the 0x10 value in data_vault.
[ 71.024560] BUG: kernel NULL pointer dereference, address:
0000000000000010
This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or
NULL value in data_vault.(CVE-2022-48703)
In the Linux kernel, the following vulnerability has been resolved:
net: marvell: prestera: Add missing of_node_put() in prestera_switch_set_base_mac_addr
This node pointer is returned by of_find_compatible_node() with
refcount incremented. Calling of_node_put() to aovid the refcount leak.(CVE-2022-48859)
In the Linux kernel, the following vulnerability has been resolved:
of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.(CVE-2023-52679)
In the Linux kernel, the following vulnerability has been resolved:
media: gspca: cpia1: shift-out-of-bounds in set_flicker
Syzkaller reported the following issue:
UBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27
shift exponent 245 is too large for 32-bit type 'int'
When the value of the variable "sd->params.exposure.gain" exceeds the
number of bits in an integer, a shift-out-of-bounds error is reported. It
is triggered because the variable "currentexp" cannot be left-shifted by
more than the number of bits in an integer. In order to avoid invalid
range during left-shift, the conditional expression is added.(CVE-2023-52764)
In the Linux kernel, the following vulnerability has been resolved:
init/main.c: Fix potential static_command_line memory overflow
We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for
static_command_line, but the strings copied into static_command_line are
extra_command_line and command_line, rather than extra_command_line and
boot_command_line.
When strlen(command_line) > strlen(boot_command_line), static_command_line
will overflow.
This patch just recovers strlen(command_line) which was miss-consolidated
with strlen(boot_command_line) in the commit f5c7310ac73e ("init/main: add
checks for the return value of memblock_alloc*()")(CVE-2024-26988)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: restore set elements when delete set fails
From abort path, nft_mapelem_activate() needs to restore refcounters to
the original state. Currently, it uses the set->ops->walk() to iterate
over these set elements. The existing set iterator skips inactive
elements in the next generation, this does not work from the abort path
to restore the original state since it has to skip active elements
instead (not inactive ones).
This patch moves the check for inactive elements to the set iterator
callback, then it reverses the logic for the .activate case which
needs to skip active elements.
Toggle next generation bit for elements when delete set command is
invoked and call nft_clear() from .activate (abort) path to restore the
next generation bit.

In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid potential panic during recovery
During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.
Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.
Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.(CVE-2024-27032)
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_core_get NULL dereference
It is possible for clk_core_get to dereference a NULL in the following
sequence:
clk_core_get()
of_clk_get_hw_from_clkspec()
__of_clk_get_hw_from_provider()
__clk_get_hw()
__clk_get_hw() can return NULL which is dereferenced by clk_core_get() at
hw->core.
Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based
clk_lookups") the check IS_ERR_OR_NULL() was performed which would have
caught the NULL.
Reading the description of this function it talks about returning NULL but
that cannot be so at the moment.
Update the function to check for hw before dereferencing it and return NULL
if hw is NULL.(CVE-2024-27038)
In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix phy_get_internal_delay accessing an empty array
The phy_get_internal_delay function could try to access to an empty
array in the case that the driver is calling phy_get_internal_delay
without defining delay_values and rx-internal-delay-ps or
tx-internal-delay-ps is defined to 0 in the device-tree.
This will lead to "unable to handle kernel NULL pointer dereference at
virtual address 0". To avoid this kernel oops, the test should be delay
>= 0. As there is already delay < 0 test just before, the test could
only be size == 0.(CVE-2024-27047)
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: add cancel_work_sync() for c2hcmd_work
The workqueue might still be running, when the driver is stopped. To
avoid a use-after-free, call cancel_work_sync() in rtl8xxxu_stop().(CVE-2024-27052)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not compare internal table flags on updates
Restore skipping transaction if table update does not modify flags.(CVE-2024-27065)
In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq27xxx-i2c: Do not free non existing IRQ
The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().
But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:

In the Linux kernel, the following vulnerability has been resolved:
fs/9p: fix uninitialized values during inode evict
If an iget fails due to not being able to retrieve information
from the server then the inode structure is only partially
initialized. When the inode gets evicted, references to
uninitialized structures (like fscache cookies) were being
made.
This patch checks for a bad_inode before doing anything other
than clearing the inode from the cache. Since the inode is
bad, it shouldn't have any state associated with it that needs
to be written back (and there really isn't a way to complete
those anyways).(CVE-2024-36923)

This is because when the log writer starts a writeback for segment summary
blocks or a super root block that use the backing device's page cache, it
does not wait for the ongoing folio/page writeback, resulting in an
inconsistent writeback state.
Fix this issue by waiting for ongoing writebacks when putting
folios/pages on the backing device into writeback state.(CVE-2024-37078)
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference
In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is
assigned to mhdp_state->current_mode, and there is a dereference of it in
drm_mode_set_name(), which will lead to a NULL pointer dereference on
failure of drm_mode_duplicate().
Fix this bug add a check of mhdp_state->current_mode.(CVE-2024-38548)

wifi: carl9170: add a proper sanity check for endpoints
Syzkaller reports [1] hitting a warning which is caused by presence
of a wrong endpoint type at the URB sumbitting stage. While there
was a check for a specific 4th endpoint, since it can switch types
between bulk and interrupt, other endpoints are trusted implicitly.
Similar warning is triggered in a couple of other syzbot issues [2].
Fix the issue by doing a comprehensive check of all endpoints
taking into account difference between high- and full-speed
configuration.

In the Linux kernel, the following vulnerability has been resolved:
media: i2c: et8ek8: Don't strip remove function when driver is builtin
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.
This also fixes a W=1 modpost warning:

In the Linux kernel, the following vulnerability has been resolved:
md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING
Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with
small possibility, the root cause is exactly the same as commit
bed9e27baf52 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"")
However, Dan reported another hang after that, and junxiao investigated
the problem and found out that this is caused by plugged bio can't issue
from raid5d().
Current implementation in raid5d() has a weird dependence:
1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear
MD_SB_CHANGE_PENDING;
2) raid5d() handles IO in a deadloop, until all IO are issued;
3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared;
This behaviour is introduce before v2.6, and for consequence, if other
context hold 'reconfig_mutex', and md_check_recovery() can't update
super_block, then raid5d() will waste one cpu 100% by the deadloop, until
'reconfig_mutex' is released.
Refer to the implementation from raid1 and raid10, fix this problem by
skipping issue IO if MD_SB_CHANGE_PENDING is still set after
md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex'
is released. Meanwhile, the hang problem will be fixed as well.(CVE-2024-39476)

liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packet
In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value,
but then it is unconditionally passed to skb_add_rx_frag() which looks
strange and could lead to null pointer dereference.
lio_vf_rep_copy_packet() call trace looks like:
octeon_droq_process_packets
octeon_droq_fast_process_packets
octeon_droq_dispatch_pkt
octeon_create_recv_info
...search in the dispatch_list...
->disp_fn(rdisp->rinfo, ...)
lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...)
In this path there is no code which sets pg_info->page to NULL.
So this check looks unneeded and doesn't solve potential problem.
But I guess the author had reason to add a check and I have no such card
and can't do real test.
In addition, the code in the function liquidio_push_packet() in
liquidio/lio_core.c does exactly the same.
Based on this, I consider the most acceptable compromise solution to
adjust this issue by moving skb_add_rx_frag() into conditional scope.

io_uring/io-wq: Use set_bit() and test_bit() at worker->flags
Utilize set_bit() and test_bit() on worker->flags within io_uring/io-wq

These races involve writes and reads to the same memory location by
different tasks running on different CPUs. To mitigate this, refactor
the code to use atomic operations such as set_bit(), test_bit(), and
clear_bit() instead of basic "and" and "or" operations. This ensures
thread-safe manipulation of worker flags.
Also, move `create_index` to avoid holes in the structure.(CVE-2024-39508)
In the Linux kernel, the following vulnerability has been resolved:
riscv: rewrite __kernel_map_pages() to fix sleeping in invalid context
__kernel_map_pages() is a debug function which clears the valid bit in page
table entry for deallocated pages to detect illegal memory accesses to
freed pages.
This function set/clear the valid bit using __set_memory(). __set_memory()
acquires init_mm's semaphore, and this operation may sleep. This is
problematic, because __kernel_map_pages() can be called in atomic context,
and thus is illegal to sleep. An example warning that this causes:

Rewrite this function with apply_to_existing_page_range(). It is fine to
not have any locking, because __kernel_map_pages() works with pages being
allocated/deallocated and those pages are not changed by anyone else in the
meantime.(CVE-2024-40915)
In the Linux kernel, the following vulnerability has been resolved:
iommu: Return right value in iommu_sva_bind_device()
iommu_sva_bind_device() should return either a sva bond handle or an
ERR_PTR value in error cases. Existing drivers (idxd and uacce) only
check the return value with IS_ERR(). This could potentially lead to
a kernel NULL pointer dereference issue if the function returns NULL
instead of an error pointer.
In reality, this doesn't cause any problems because iommu_sva_bind_device()
only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.
In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will
return an error, and the device drivers won't call iommu_sva_bind_device()
at all.(CVE-2024-40945)

Commit c7423dbdbc9e ("ima: Handle -ESTALE returned by
ima_filter_rule_match()") introduced call to ima_lsm_copy_rule within a
RCU read-side critical section which contains kmalloc with GFP_KERNEL.
This implies a possible sleep and violates limitations of RCU read-side
critical sections on non-PREEMPT systems.
Sleeping within RCU read-side critical section might cause
synchronize_rcu() returning early and break RCU protection, allowing a
UAF to happen.
The root cause of this issue could be described as follows:
| Thread A | Thread B |
| |ima_match_policy |
| | rcu_read_lock |
|ima_lsm_update_rule | |
| synchronize_rcu | |
| | kmalloc(GFP_KERNEL)|
| | sleep |
==> synchronize_rcu returns early
| kfree(entry) | |
| | entry = entry->next|
==> UAF happens and entry now becomes NULL (or could be anything).
| | entry->action |
==> Accessing entry might cause panic.
To fix this issue, we are converting all kmalloc that is called within
RCU read-side critical section to use GFP_ATOMIC.

trace_drop_common() also disables interrupts, but this is a minor issue
because we could easily replace it with a local_lock.
Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic
context.(CVE-2024-40980)
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: bypass empty buckets in batadv_purge_orig_ref()
Many syzbot reports are pointing to soft lockups in
batadv_purge_orig_ref() [1]
Root cause is unknown, but we can avoid spending too much
time there and perhaps get more interesting reports.

---truncated---(CVE-2024-40981)
In the Linux kernel, the following vulnerability has been resolved:
ssb: Fix potential NULL pointer dereference in ssb_device_uevent()
The ssb_device_uevent() function first attempts to convert the 'dev' pointer
to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before
performing the NULL check, potentially leading to a NULL pointer
dereference if 'dev' is NULL.
To fix this issue, move the NULL check before dereferencing the 'dev' pointer,
ensuring that the pointer is valid before attempting to use it.
Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2024-40982)
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()
syzbot found hanging tasks waiting on rtnl_lock [1]
A reproducer is available in the syzbot bug.
When a request to add multiple actions with the same index is sent, the
second request will block forever on the first request. This holds
rtnl_lock, and causes tasks to hang.
Return -EAGAIN to prevent infinite looping, while keeping documented
behavior.

In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.(CVE-2024-41011)</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: Unregister clocks/resets when unbinding
Currently, unbinding a CCU driver unmaps the device's MMIO region, while
leaving its clocks/resets and their providers registered. This can cause
a page fault later when some clock operation tries to perform MMIO. Fix
this by separating the CCU initialization from the memory allocation,
and then using a devres callback to unregister the clocks and resets.
This also fixes a memory leak of the `struct ccu_reset`, and uses the
correct owner (the specific platform driver) for the clocks and resets.
Early OF clock providers are never unregistered, and limited error
handling is possible, so they are mostly unchanged. The error reporting
is made more consistent by moving the message inside of_sunxi_ccu_probe.</Note>

<Note Title="Vulnerability Description" Type="General" Ordinal="4" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.</Note>

shift exponent 245 is too large for 32-bit type 'int'
When the value of the variable "sd->params.exposure.gain" exceeds the
number of bits in an integer, a shift-out-of-bounds error is reported. It
is triggered because the variable "currentexp" cannot be left-shifted by
more than the number of bits in an integer. In order to avoid invalid

<Note Title="Vulnerability Description" Type="General" Ordinal="6" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
init/main.c: Fix potential static_command_line memory overflow
We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for
static_command_line, but the strings copied into static_command_line are
extra_command_line and command_line, rather than extra_command_line and
boot_command_line.
When strlen(command_line) > strlen(boot_command_line), static_command_line
will overflow.
This patch just recovers strlen(command_line) which was miss-consolidated
with strlen(boot_command_line) in the commit f5c7310ac73e ("init/main: add

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="7" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: restore set elements when delete set fails
From abort path, nft_mapelem_activate() needs to restore refcounters to
the original state. Currently, it uses the set->ops->walk() to iterate
over these set elements. The existing set iterator skips inactive
elements in the next generation, this does not work from the abort path
to restore the original state since it has to skip active elements
instead (not inactive ones).
This patch moves the check for inactive elements to the set iterator
callback, then it reverses the logic for the .activate case which
needs to skip active elements.
Toggle next generation bit for elements when delete set command is
invoked and call nft_clear() from .activate (abort) path to restore the
next generation bit.

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="8" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid potential panic during recovery
During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.
Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.
Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="9" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_core_get NULL dereference
It is possible for clk_core_get to dereference a NULL in the following
sequence:
clk_core_get()
of_clk_get_hw_from_clkspec()
__of_clk_get_hw_from_provider()
__clk_get_hw()
__clk_get_hw() can return NULL which is dereferenced by clk_core_get() at
hw->core.
Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based
clk_lookups") the check IS_ERR_OR_NULL() was performed which would have
caught the NULL.
Reading the description of this function it talks about returning NULL but
that cannot be so at the moment.
Update the function to check for hw before dereferencing it and return NULL
if hw is NULL.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="10" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix phy_get_internal_delay accessing an empty array
The phy_get_internal_delay function could try to access to an empty
array in the case that the driver is calling phy_get_internal_delay
without defining delay_values and rx-internal-delay-ps or
tx-internal-delay-ps is defined to 0 in the device-tree.
This will lead to "unable to handle kernel NULL pointer dereference at
virtual address 0". To avoid this kernel oops, the test should be delay
>= 0. As there is already delay < 0 test just before, the test could
only be size == 0.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="18" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
fs/9p: fix uninitialized values during inode evict
If an iget fails due to not being able to retrieve information
from the server then the inode structure is only partially
initialized. When the inode gets evicted, references to
uninitialized structures (like fscache cookies) were being
made.
This patch checks for a bad_inode before doing anything other
than clearing the inode from the cache. Since the inode is
bad, it shouldn't have any state associated with it that needs
to be written back (and there really isn't a way to complete
those anyways).</Note>

This is because when the log writer starts a writeback for segment summary
blocks or a super root block that use the backing device's page cache, it
does not wait for the ongoing folio/page writeback, resulting in an
inconsistent writeback state.
Fix this issue by waiting for ongoing writebacks when putting
folios/pages on the backing device into writeback state.</Note>

wifi: carl9170: add a proper sanity check for endpoints
Syzkaller reports [1] hitting a warning which is caused by presence
of a wrong endpoint type at the URB sumbitting stage. While there
was a check for a specific 4th endpoint, since it can switch types
between bulk and interrupt, other endpoints are trusted implicitly.
Similar warning is triggered in a couple of other syzbot issues [2].
Fix the issue by doing a comprehensive check of all endpoints
taking into account difference between high- and full-speed
configuration.

<Note Title="Vulnerability Description" Type="General" Ordinal="26" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING
Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with
small possibility, the root cause is exactly the same as commit
bed9e27baf52 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"")
However, Dan reported another hang after that, and junxiao investigated
the problem and found out that this is caused by plugged bio can't issue
from raid5d().
Current implementation in raid5d() has a weird dependence:
1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear
MD_SB_CHANGE_PENDING;
2) raid5d() handles IO in a deadloop, until all IO are issued;
3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared;
This behaviour is introduce before v2.6, and for consequence, if other
context hold 'reconfig_mutex', and md_check_recovery() can't update
super_block, then raid5d() will waste one cpu 100% by the deadloop, until
'reconfig_mutex' is released.
Refer to the implementation from raid1 and raid10, fix this problem by
skipping issue IO if MD_SB_CHANGE_PENDING is still set after
md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex'
is released. Meanwhile, the hang problem will be fixed as well.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="28" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packet
In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value,
but then it is unconditionally passed to skb_add_rx_frag() which looks
strange and could lead to null pointer dereference.
lio_vf_rep_copy_packet() call trace looks like:
octeon_droq_process_packets
octeon_droq_fast_process_packets
octeon_droq_dispatch_pkt
octeon_create_recv_info
...search in the dispatch_list...
->disp_fn(rdisp->rinfo, ...)
lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...)
In this path there is no code which sets pg_info->page to NULL.
So this check looks unneeded and doesn't solve potential problem.
But I guess the author had reason to add a check and I have no such card
and can't do real test.
In addition, the code in the function liquidio_push_packet() in
liquidio/lio_core.c does exactly the same.
Based on this, I consider the most acceptable compromise solution to
adjust this issue by moving skb_add_rx_frag() into conditional scope.

Utilize set_bit() and test_bit() on worker->flags within io_uring/io-wq

The structure io_worker->flags may be accessed through various data

These races involve writes and reads to the same memory location by
different tasks running on different CPUs. To mitigate this, refactor
the code to use atomic operations such as set_bit(), test_bit(), and
clear_bit() instead of basic "and" and "or" operations. This ensures
thread-safe manipulation of worker flags.
Also, move `create_index` to avoid holes in the structure.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="31" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
iommu: Return right value in iommu_sva_bind_device()
iommu_sva_bind_device() should return either a sva bond handle or an
ERR_PTR value in error cases. Existing drivers (idxd and uacce) only
check the return value with IS_ERR(). This could potentially lead to
a kernel NULL pointer dereference issue if the function returns NULL
instead of an error pointer.
In reality, this doesn't cause any problems because iommu_sva_bind_device()
only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.
In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will
return an error, and the device drivers won't call iommu_sva_bind_device()
at all.</Note>

Commit c7423dbdbc9e ("ima: Handle -ESTALE returned by
ima_filter_rule_match()") introduced call to ima_lsm_copy_rule within a
RCU read-side critical section which contains kmalloc with GFP_KERNEL.
This implies a possible sleep and violates limitations of RCU read-side
critical sections on non-PREEMPT systems.
Sleeping within RCU read-side critical section might cause
synchronize_rcu() returning early and break RCU protection, allowing a
UAF to happen.
The root cause of this issue could be described as follows:
| Thread A | Thread B |
| |ima_match_policy |
| | rcu_read_lock |
|ima_lsm_update_rule | |
| synchronize_rcu | |
| | kmalloc(GFP_KERNEL)|
| | sleep |
==> synchronize_rcu returns early
| kfree(entry) | |
| | entry = entry->next|
==> UAF happens and entry now becomes NULL (or could be anything).
| | entry->action |
==> Accessing entry might cause panic.
To fix this issue, we are converting all kmalloc that is called within
RCU read-side critical section to use GFP_ATOMIC.

trace_drop_common() also disables interrupts, but this is a minor issue
because we could easily replace it with a local_lock.
Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic
context.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="40" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:
ssb: Fix potential NULL pointer dereference in ssb_device_uevent()
The ssb_device_uevent() function first attempts to convert the 'dev' pointer
to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before
performing the NULL check, potentially leading to a NULL pointer
dereference if 'dev' is NULL.
To fix this issue, move the NULL check before dereferencing the 'dev' pointer,
ensuring that the pointer is valid before attempting to use it.
Found by Linux Verification Center (linuxtesting.org) with SVACE.</Note>

net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()
syzbot found hanging tasks waiting on rtnl_lock [1]
A reproducer is available in the syzbot bug.
When a request to add multiple actions with the same index is sent, the
second request will block forever on the first request. This holds
rtnl_lock, and causes tasks to hang.
Return -EAGAIN to prevent infinite looping, while keeping documented
behavior.

drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.</Note>
