Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
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： ASoC: sti: 在申请中断之前初始化 IRQ 锁 函数在初始化 之前就注册了共享中断。如果中断在此时挂起，可能会在中断处理程序运行时触发，而此时锁仍处于未初始化状态。 应先初始化锁，再注册中断，以确保中断路径始终看到有效的锁状态。

Vulnerability Title
ASoC: sti: initialize IRQ lock before requesting IRQ
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: sti: initialize IRQ lock before requesting IRQ
uni_reader_init() registers the shared IRQ before initializing
reader->irq_lock. A pending interrupt can invoke the handler while the
lock is still uninitialized.
Initialize the lock before registering the IRQ so the interrupt path
always sees valid lock state.
