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. (NVD)
