Summary
alsa-lib through 1.2.16.1 contains a stack buffer overflow in the __snd_ctl_ascii_elem_id_parse() function that writes one byte past a 64-byte buffer when parsing a name= field with 64 or more characters. Attackers can supply a long control-element identifier string through saved state files or command-line arguments to overwrite adjacent stack memory and crash the calling process.
Risk Assessment
An attacker can remotely or locally crash a process using alsa-lib, leading to a denial of service (DoS), and potentially to arbitrary code execution.
Recommendation
Upgrade alsa-lib to a version newer than 1.2.16.1 that contains the fix for this vulnerability.
Other vulnerabilities in alsa-lib
See all- CVE-2026-96675Low
alsa-lib through 1.2.16.1 contains a denial of service vulnerability in the multi PCM plugin that fails to validate sparse binding indices before array access. Attackers can supply a malicious ALSA configuration file with sparse bindings to trigger an out-of-bounds array read and assertion failure, causing the application to abort.
- CVE-2026-96674Medium
alsa-lib through 1.2.16.1 computes combined topology element size using 32-bit arithmetic in src/topology/ctl.c, allowing integer overflow that defeats bounds checks. Attackers can supply crafted topology files that wrap size calculations, causing the decoder to read beyond the topology buffer.
