Last modified
CVE-2026-90781 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. 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.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
