Echo: alsa-lib: security update to 1.2.14-1+e2

high Tenable Self-Hosted Container Security Plugin ID 455161

Description

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

 - The Advanced Linux Sound Architecture (ALSA) library before 1.2.16.1 contains a double-free vulnerability
 in parse_def() in src/conf.c that allows attackers to corrupt memory by supplying maliciously crafted ALSA
 configuration text. When parsing nested compound or array configuration blocks, parse_def() fails to check
 return values before continuing, causing snd_config_delete() to be called twice on the same already-freed
 node, resulting in a NULL-pointer write or invalid memory read. (CVE-2026-56109)

Solution

Update the alsa-lib library and its related packages to version 1.2.14-1+e2 or later.
