Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 460153

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: ALSA: usb-audio: Use correct version
 for UAC3 header validation The entry of the validators table for UAC3 AC header descriptor is defined with
 the wrong protocol version UAC_VERSION_2, while it should have been UAC_VERSION_3. This results in the
 validator never matching for actual UAC3 devices (protocol == UAC_VERSION_3), causing their header
 descriptors to bypass validation entirely. A malicious USB device presenting a truncated UAC3 header could
 exploit this to cause out-of-bounds reads when the driver later accesses unvalidated descriptor fields.
 The bug was introduced in the same commit as the recently fixed UAC3 feature unit sub-type typo, and
 appears to be from the same copy-paste error when the UAC3 section was created from the UAC2 section.
 (CVE-2026-23318)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
