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.

Applying the patch f84cd4ced7b36fddb8e4ee24404cf7c091d27020 is able to eliminate this problem.
