CVE-2026-89979

CVE-2026-89979 is a race condition in the Linux kernel ALSA PCM subsystem. Non-atomic operations (hw_params, hw_free, prepare) can be in progress when another thread issues an atomic PCM trigger-start , causing state inconsistency (e.g., ODEBUG warnings reported by syzkaller ). The CVSS 3.1 score...
