CVE-2026-80967

HighCVSS 8.4/10Last modified Oct 19, 2026

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.
