Description

alsa-lib security update

The alsa-lib is a library to interface with ALSA in the Linux kernel and virtual devices using a plugin system. More detail: https://alsa.opensrc.org/Alsa-lib

Security Fix(es):

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)
