Detailsinfo

A vulnerability was found in ALSA Project alsa-lib up to 1.2.16.1. It has been classified as problematic. This affects the function __snd_ctl_ascii_elem_id_parse of the component Control Element Identifier Parsing. The manipulation of the argument name with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-90781 since 09/13/2026. The exploitability is told to be easy. Attacking locally is a requirement. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit.
