CVE-2026-80967

A flaw was found in the ALSA pcxhr driver within the Linux kernel. The pcxhrprobe function requests a threaded interrupt before properly initializing a critical mutex mgr-lock. This oversight could allow an early interrupt to operate on an uninitialized mutex, potentially leading to system...

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcxhr: initialize mutexes before requesting threaded IRQ pcxhrprobe requests pcxhrthreadedirq before initializing mgr-lock, even though the threaded handler takes that mutex. Initialize the manager locks before...

CVE-2026-80967

CVE-2026-80967 affects the Linux kernel 's ALSA pcxhr (O2 Micro) audio driver. The root cause is an initialization-order bug in pcxhr_probe(): the driver calls request_threaded_irq() before initializing mgr->lock, meaning an early interrupt during probe could trigger the threaded handler again...
