Security Fix(es):
|
|
|
|
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_SESSION_SETUP commands. The issue results from the lack of control of resource consumption. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.(CVE-2023-32247)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
|
|
|
|
When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances.
|
|
|
|
We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.
|
|
|
|
(CVE-2023-3777)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
|
|
|
|
On an error when building a nftables rule, deactivating immediate expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used.
|
|
|
|
We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2.
|
|
|
|
(CVE-2023-4015)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation.
|
|
|
|
When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free.
|
|
|
|
We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.
|
|
|
|
(CVE-2023-4206)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation.
|
|
|
|
When fw_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free.
|
|
|
|
We recommend upgrading past commit 76e42ae831991c828cffa8c37736ebfb831ad5ec.
|
|
|
|
(CVE-2023-4207)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.
|
|
|
|
When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free.
|
|
|
|
We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.
|
|
|
|
(CVE-2023-4208)
|
|
|
|
A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation.
|
|
|
|
The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free.
|
|
|
|
We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c.

<Note Title="Vulnerability Description" Type="General" Ordinal="4" xml:lang="en">A use-after-free vulnerability in the Linux kernel s net/sched: cls_route component can be exploited to achieve local privilege escalation.When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free.We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.</Note>

<Notes>
|
|
<Note Title="Vulnerability Description" Type="General" Ordinal="7" xml:lang="en">A use-after-free vulnerability in the Linux kernel s af_unix component can be exploited to achieve local privilege escalation.The unix_stream_sendpage() function tries to add data to the last skb in the peer s recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free.We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c.</Note>
