low Tenable Cloud Security Plugin ID 471901

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/mlx5: HWS, fix matcher leak on
 resize target setup failure hws_bwc_matcher_move() allocates a replacement matcher before setting it as
 the resize target. If mlx5hws_matcher_resize_set_target() fails, the replacement matcher is not attached
 anywhere and is leaked. Fix the leak by destroying the replacement matcher before returning from the
 resize-target failure path. The bug was first flagged by an experimental analysis tool we are developing
 for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is
 not yet publicly available. Manual inspection confirms that the bug is still present in v7.1.1. An x86_64
 allyesconfig build showed no new warnings. As we do not have a mlx5 HWS-capable device to test with, no
 runtime testing was able to be performed. (CVE-2026-72032)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
