Google: sys-kernel/lakitu-kernel-6_1: security update to 17872.0.0

high Tenable Self-Hosted Container Security Plugin ID 451620

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 (or backported equivalents).
(CVE-2023-4622)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 17872.0.0 or later.
