- 8.4 HIGH — CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Description
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.
