CVE-2026-90781 is fixed in alsa-lib on 1 platform by DEBIAN-CVE-2026-90781 (version 1.2.16.1-2), released October 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
