Quick assessment

Affected
Linux Linux
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： 媒体子系统：chips-media: wave5：从实例列表中移除后释放 m2m_ctx 如果 IRQ 线程在释放 m2m_ctx 与 wave5_release 函数将流实例从活动实例列表中移除之间成功获取自旋锁，则可能导致释放后使用（use-after-free）漏洞。IRQ 线程查找的 m2m_ctx 已被释放，从而引发空指针解引用。

media: chips-media: wave5: Release m2m_ctx after Instance Removed from List
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Release m2m_ctx after Instance Removed from List Possible use after free if IRQ thread manages to obtain spinlock between m2m_ctx release and wave5_release function removing stream instance from list of active instances. The IRQ thread looks for the m2m_ctx which is freed so null pointer dereference occurs.
