CVE-2026-56109

The CVE concerns ALSA Library prior to 1.2.16.1, where a double-free occurs in parse_def() (src/conf.c) due to not validating return values when parsing nested compound or array configuration blocks. This can cause snd_config_delete() to be invoked twice on an already-freed node, leading to NULL-...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

USN-8044-2 alsa-lib vulnerability

USN-8044-1 fixed a vulnerability in alsa-lib. This update provides the corresponding fix for alsa-lib on Ubuntu 20.04 LTS. Original advisory details: It was discovered that alsa-lib incorrectly handled the topology mixer control decoder. A local attacker could use a specially crafted topology fil...

CVE-2026-46146 ALSA: usb-audio: Avoid potential endless loop in convert_chmap_v3()

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Avoid potential endless loop in convertchmapv3 The convertchmapv3 has a loop with its increment size of csdesc-wLength, but we forgot to validate csdesc-wLength itself, which may lead to potential endless loop by...

CVE-2026-46088

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA control component. Improper validation of the buffer length before a string length operation in the sndctleleminitenumnames function can lead to a system panic. This vulnerability could allow a local attacker to trigger...
