Google: sys-kernel/csql-kernel-6_1, sys-kernel/csql-kernel-6_6: security update to 18613.534.53

high Tenable Cloud Security Plugin ID 466266

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: apparmor: fix unprivileged local user
 can do privileged policy management An unprivileged local user can load, replace, and remove profiles by
 opening the apparmorfs interfaces, via a confused deputy attack, by passing the opened fd to a privileged
 process, and getting the privileged process to write to the interface. This does require a privileged
 target that can be manipulated to do the write for the unprivileged process, but once such access is
 achieved full policy management is possible and all the possible implications that implies: removing
 confinement, DoS of system or target applications by denying all execution, by-passing the unprivileged
 user namespace restriction, to exploiting kernel bugs for a local privilege escalation. The policy
 management interface can not have its permissions simply changed from 0666 to 0600 because non-root
 processes need to be able to load policy to different policy namespaces. Instead ensure the task writing
 the interface has privileges that are a subset of the task that opened the interface. This is already done
 via policy for confined processes, but unconfined can delegate access to the opened fd, by-passing the
 usual policy check. (CVE-2026-23268)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.53 or later.
