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.

CVE-2023-4622 CVE-2023-4622: In unix_stream_sendpage of af_unix
In unix_stream_sendpage of af_unix.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

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.

It was discovered that the Xen netback driver in the Linux kernel did not
properly handle packets structured in certain ways. An attacker in a guest
VM could possibly use this to cause a denial of service (host NIC
availability).(CVE-2022-3643)
It was discovered that the virtual terminal driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly expose sensitive
information (kernel memory).(CVE-2023-3567)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

CVE-2023-4622 [HIGH] CWE-416 kernel: use after free in unix_stream_sendpage
kernel: use after free in unix_stream_sendpage
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.
