Unknown · Alsa Library · CVE-2026-56109
**Name of the Vulnerable Software and Affected Versions**
ALSA library versions prior to 1.2.16.1
**Description**
A double-free issue exists in the `parse def()` function within `src/conf.c`. This occurs when the system parses nested compound or array configuration blocks and fails to check return values before proceeding. Consequently, the `snd config delete()` function is called twice on the same already-freed node, which can lead to memory corruption, a NULL-pointer write, or an invalid memory read if an attacker provides maliciously crafted ALSA configuration text.
**Recommendations**
Update ALSA library to version 1.2.16.1.
