Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 462440

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: char: applicom: fix NULL pointer
 dereference in ac_ioctl Discovered by Atuin - Automated Vulnerability Discovery Engine. In ac_ioctl, the
 validation of IndexCard and the check for a valid RamIO pointer are skipped when cmd is 6. However, the
 function unconditionally executes readb(apbs[IndexCard].RamIO + VERS) at the end. If cmd is 6, IndexCard
 may reference a board that does not exist (where RamIO is NULL), leading to a NULL pointer dereference.
 Fix this by skipping the readb access when cmd is 6, as this command is a global information query and
 does not target a specific board context. (CVE-2025-68797)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
