## Overview

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

ALSA: harmony: initialize locks before requesting IRQ

snd_harmony_create() registers the IRQ before initializing h->lock and
h->mixer_lock. A pending interrupt can invoke the handler while these
locks are uninitialized.

Initialize both locks before requesting the IRQ so the handler always
sees valid lock state.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
