Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.220.174

medium Tenable Cloud Security Plugin ID 469256

Description

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

- In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent concurrent access
to IPSec ASO context The query or updating IPSec offload object is through Access ASO WQE. The driver uses
a single mlx5e_ipsec_aso struct for each PF, which contains a shared DMA-mapped context for all ASO
operations. A race condition exists because the ASO spinlock is released before the hardware has finished
processing WQE. If a second operation is initiated immediately after, it overwrites the shared context in
the DMA area. When the first operation's completion is processed later, it reads this corrupted context,
leading to unexpected behavior and incorrect results. This commit fixes the race by introducing a private
context within each IPSec offload object. The shared ASO context is now copied to this private context
while the ASO spinlock is held. Subsequent processing uses this saved, per-object context, ensuring its
integrity is maintained. (CVE-2026-23441)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.220.174 or later.
