Ubuntu Security Notice USN-8044-1
February 16, 2026

alsa-lib vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

alsa-lib could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- alsa-lib: shared library for ALSA applications

Details:

It was discovered that alsa-lib incorrectly handled the topology mixer
control decoder. A local attacker could use a specially crafted topology
file to cause alsa-lib to crash, resulting in a denial of service, or
possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.10
  libasound2t64                   1.2.14-1ubuntu1.1

Ubuntu 24.04 LTS
  libasound2t64                   1.2.11-1ubuntu0.2

Ubuntu 22.04 LTS
  libasound2                      1.2.6.1-1ubuntu1.1

In general, a standard system update will make all the necessary changes.
