# CVE-2026-80967

## Summary

- **CVE ID:** CVE-2026-80967
- **Severity:** HIGH
- **CVSS Score:** 8.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
- **CWE:** N/A

## 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.
