Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： ALSA: harmony：在请求中断（IRQ）之前初始化锁 在初始化 和 之前注册了 IRQ。此时若有待处理的中断，可能在锁尚未初始化时触发中断处理函数。 应在请求 IRQ 之前初始化这两个锁，以确保中断处理函数始终看到有效的锁状态。

Vulnerability Title
ALSA: harmony: initialize locks before requesting IRQ
Source: CVE Program / CVE List V5
Vulnerability Description
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.
