CVE-2022-49498

CVE-2022-49498 affects the Linux kernel, specifically the ALSA PCM path. The issue: a pointer substream could be dereferenced before a null check (PCM_RUNTIME_CHECK), risking a crash/denial of service if triggered locally. The connected advisories (e.g., Astra Linux, SUSE SU-2025 updates) confirm...
