EulerOS 2.0 SP12 : alsa-lib (EulerOS-SA-2026-3322)

high Nessus Plugin ID 343744

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the alsa-lib packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 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)

Tenable has extracted the preceding description block directly from the EulerOS alsa-lib security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected alsa-lib packages.
