EulerOS Virtualization 2.13.0 : alsa-lib (EulerOS-SA-2026-2157)

medium Nessus Plugin ID 319416

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 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)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization 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.
