Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

media: mediatek: vcodec: Only free buffer VA that is not NULL

In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly
called only when the buffer to free exists, there are some instances
that didn&apos;t do the check and triggered warnings in practice.

We believe those checks were forgotten unintentionally. Add the checks
back to fix the warnings.(CVE-2023-52888)

In the Linux kernel, the following vulnerability has been resolved:

HID: core: remove unnecessary WARN_ON() in implement()

Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.

Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
	...
	value &amp;= m;
	...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list

Use list_for_each_entry_safe() to allow iterating through the list and
deleting the entry in the iteration process. The descriptor is freed via
idxd_desc_complete() and there&apos;s a slight chance may cause issue for
the list iterator when the descriptor is reused by another thread
without it being deleted from the list.(CVE-2024-40956)

In the Linux kernel, the following vulnerability has been resolved:

RDMA/mlx5: Add check for srq max_sge attribute

max_sge attribute is passed by the user, and is inserted and used
unchecked, so verify that the value doesn&apos;t exceed maximum allowed value
before using it.(CVE-2024-40990)

In the Linux kernel, the following vulnerability has been resolved:

USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor

Syzbot has identified a bug in usbcore (see the Closes: tag below)
caused by our assumption that the reserved bits in an endpoint
descriptor&apos;s bEndpointAddress field will always be 0.  As a result of
the bug, the endpoint_is_duplicate() routine in config.c (and possibly
other routines as well) may believe that two descriptors are for
distinct endpoints, even though they have the same direction and
endpoint number.  This can lead to confusion, including the bug
identified by syzbot (two descriptors with matching endpoint numbers
and directions, where one was interrupt and the other was bulk).

To fix the bug, we will clear the reserved bits in bEndpointAddress
when we parse the descriptor.  (Note that both the USB-2.0 and USB-3.1
specs say these bits are &quot;Reserved, reset to zero&quot;.)  This requires us
to make a copy of the descriptor earlier in usb_parse_endpoint() and
use the copy instead of the original when checking for duplicates.(CVE-2024-41035)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: prefer nft_chain_validate

nft_chain_validate already performs loop detection because a cycle will
result in a call stack overflow (ctx-&gt;level &gt;= NFT_JUMP_STACK_SIZE).

It also follows maps via -&gt;validate callback in nft_lookup, so there
appears no reason to iterate the maps again.

nf_tables_check_loops() and all its helper functions can be removed.
This improves ruleset load time significantly, from 23s down to 12s.

This also fixes a crash bug. Old loop detection code can result in
unbounded recursion:

BUG: TASK stack guard page was hit at ....
Oops: stack guard page: 0000 [#1] PREEMPT SMP KASAN
CPU: 4 PID: 1539 Comm: nft Not tainted 6.10.0-rc5+ #1
[..]

with a suitable ruleset during validation of register stores.

I can&apos;t see any actual reason to attempt to check for this from
nft_validate_register_store(), at this point the transaction is still in
progress, so we don&apos;t have a full picture of the rule graph.

For nf-next it might make sense to either remove it or make this depend
on table-&gt;validate_state in case we could catch an error earlier
(for improved error reporting to userspace).(CVE-2024-41042)

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: lantiq_etop: fix double free in detach

The number of the currently released descriptor is never incremented
which results in the same skb being released multiple times.(CVE-2024-41046)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix inode number range checks

Patch series &quot;nilfs2: fix potential issues related to reserved inodes&quot;.

This series fixes one use-after-free issue reported by syzbot, caused by
nilfs2&apos;s internal inode being exposed in the namespace on a corrupted
filesystem, and a couple of flaws that cause problems if the starting
number of non-reserved inodes written in the on-disk super block is
intentionally (or corruptly) changed from its default value.  


This patch (of 3):

In the current implementation of nilfs2, &quot;nilfs-&gt;ns_first_ino&quot;, which
gives the first non-reserved inode number, is read from the superblock,
but its lower limit is not checked.

As a result, if a number that overlaps with the inode number range of
reserved inodes such as the root directory or metadata files is set in the
super block parameter, the inode number test macros (NILFS_MDT_INODE and
NILFS_VALID_INODE) will not function properly.

In addition, these test macros use left bit-shift calculations using with
the inode number as the shift count via the BIT macro, but the result of a
shift calculation that exceeds the bit width of an integer is undefined in
the C specification, so if &quot;ns_first_ino&quot; is set to a large value other
than the default value NILFS_USER_INO (=11), the macros may potentially
malfunction depending on the environment.

Fix these issues by checking the lower bound of &quot;nilfs-&gt;ns_first_ino&quot; and
by preventing bit shifts equal to or greater than the NILFS_USER_INO
constant in the inode number test macros.

Also, change the type of &quot;ns_first_ino&quot; from signed integer to unsigned
integer to avoid the need for type casting in comparisons such as the
lower bound check introduced this time.(CVE-2024-42105)

In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

syzbot is able to trigger softlockups, setting NL80211_ATTR_TXQ_QUANTUM
to 2^31.

We had a similar issue in sch_fq, fixed with commit
d9e15a273306 (&quot;pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM&quot;)

HID: core: remove unnecessary WARN_ON() in implement()

Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.

Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
	...
	value &amp;= m;
	...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor

Syzbot has identified a bug in usbcore (see the Closes: tag below)
caused by our assumption that the reserved bits in an endpoint
descriptor&apos;s bEndpointAddress field will always be 0.  As a result of
the bug, the endpoint_is_duplicate() routine in config.c (and possibly
other routines as well) may believe that two descriptors are for
distinct endpoints, even though they have the same direction and
endpoint number.  This can lead to confusion, including the bug
identified by syzbot (two descriptors with matching endpoint numbers
and directions, where one was interrupt and the other was bulk).

To fix the bug, we will clear the reserved bits in bEndpointAddress
when we parse the descriptor.  (Note that both the USB-2.0 and USB-3.1
specs say these bits are &quot;Reserved, reset to zero&quot;.)  This requires us
to make a copy of the descriptor earlier in usb_parse_endpoint() and
use the copy instead of the original when checking for duplicates.</Note>

		<Notes>
			<Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: prefer nft_chain_validate

nft_chain_validate already performs loop detection because a cycle will
result in a call stack overflow (ctx-&gt;level &gt;= NFT_JUMP_STACK_SIZE).

It also follows maps via -&gt;validate callback in nft_lookup, so there
appears no reason to iterate the maps again.

nf_tables_check_loops() and all its helper functions can be removed.
This improves ruleset load time significantly, from 23s down to 12s.

This also fixes a crash bug. Old loop detection code can result in
unbounded recursion:

BUG: TASK stack guard page was hit at ....
Oops: stack guard page: 0000 [#1] PREEMPT SMP KASAN
CPU: 4 PID: 1539 Comm: nft Not tainted 6.10.0-rc5+ #1
[..]

with a suitable ruleset during validation of register stores.

I can&apos;t see any actual reason to attempt to check for this from
nft_validate_register_store(), at this point the transaction is still in
progress, so we don&apos;t have a full picture of the rule graph.

For nf-next it might make sense to either remove it or make this depend
on table-&gt;validate_state in case we could catch an error earlier
(for improved error reporting to userspace).</Note>

			<Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix inode number range checks

Patch series &quot;nilfs2: fix potential issues related to reserved inodes&quot;.

This series fixes one use-after-free issue reported by syzbot, caused by
nilfs2&apos;s internal inode being exposed in the namespace on a corrupted
filesystem, and a couple of flaws that cause problems if the starting
number of non-reserved inodes written in the on-disk super block is
intentionally (or corruptly) changed from its default value.  


This patch (of 3):

In the current implementation of nilfs2, &quot;nilfs-&gt;ns_first_ino&quot;, which
gives the first non-reserved inode number, is read from the superblock,
but its lower limit is not checked.

As a result, if a number that overlaps with the inode number range of
reserved inodes such as the root directory or metadata files is set in the
super block parameter, the inode number test macros (NILFS_MDT_INODE and
NILFS_VALID_INODE) will not function properly.

In addition, these test macros use left bit-shift calculations using with
the inode number as the shift count via the BIT macro, but the result of a
shift calculation that exceeds the bit width of an integer is undefined in
the C specification, so if &quot;ns_first_ino&quot; is set to a large value other
than the default value NILFS_USER_INO (=11), the macros may potentially
malfunction depending on the environment.

Fix these issues by checking the lower bound of &quot;nilfs-&gt;ns_first_ino&quot; and
by preventing bit shifts equal to or greater than the NILFS_USER_INO
constant in the inode number test macros.

Also, change the type of &quot;ns_first_ino&quot; from signed integer to unsigned
integer to avoid the need for type casting in comparisons such as the
lower bound check introduced this time.</Note>
