Description Vladimir Vasilev 2026-09-23 18:23:15 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
