Echo: alsa-lib: security update to 1.2.14-1+e1

medium Tenable Self-Hosted Container Security Plugin ID 463181

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - alsa-lib versions 1.2.2 up to and including 1.2.15.2, prior to commit 5f7fe33, contain a heap-based buffer
 overflow in the topology mixer control decoder. The tplg_decode_control_mixer1() function reads the
 num_channels field from untrusted .tplg data and uses it as a loop bound without validating it against the
 fixed-size channel array (SND_TPLG_MAX_CHAN). A crafted topology file with an excessive num_channels value
 can cause out-of-bounds heap writes, leading to a crash. (CVE-2026-25068)

Solution

Update the alsa-lib library and its related packages to version 1.2.14-1+e1 or later.
