In the Linux kernel, the following vulnerability has been resolved:

ALSA: pcxhr: initialize mutexes before requesting threaded IRQ

pcxhr probe() requests pcxhr threaded irq() before initializing mgr->lock, even though the threaded handler takes that mutex.

Initialize the manager locks before request threaded irq() so an early interrupt cannot run against uninitialized mutex state during probe.
