Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 459619

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: hda/conexant: Fix missing error
 check for jack detection In cx_probe(), the return value of snd_hda_jack_detect_enable_callback() is
 ignored. This function returns a pointer, and if it fails (e.g., due to memory allocation failure), it
 returns an error pointer which must be checked using IS_ERR(). If the registration fails, the driver
 continues to probe, but the jack detection callback will not be registered. This can lead to a kernel
 crash later when the driver attempts to handle jack events or accesses the uninitialized structure. Check
 the return value using IS_ERR() and propagate the error via PTR_ERR() to the probe caller.
 (CVE-2026-53291)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
