CVE-2026-80628

CVE-2026-80628 is a data race in the Linux kernel's ALSA sequencer OSS subsystem. The function snd_seq_oss_readq_clear() resets ring queue state (qlen, head, tail) without holding the q->lock spinlock, while the normal reader and producer paths serialize the same state under that lock. This ra...
