CVE-2026-89980
Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: harmony: initialize locks before requesting IRQ
snd_harmony_create() registers the IRQ before initializing h->lock and h->mixer_lock. A pending interrupt can invoke the handler while these locks are uninitialized.
Initialize both locks before requesting the IRQ so the handler always sees valid lock state.
