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： OPP：修复清理顺序问题 提交 173e02d67494（“OPP: 内联初始化作用域指针”）为所有指针添加了初始化代码。在某些情况下，初始化顺序被改变，导致 opp_table 在 opp 之后才被初始化。这一变化同时也改变了已注册的清理函数的执行顺序。 当执行清理操作时，如果在最后一个引用被释放时，释放函数 _opp_kref_release 尝试访问已经释放的 opp->opp_table，就可能引发“使用后释放”（use-after-free）错误。 通过恢复将 o

Vulnerability Title
OPP: Fix cleanup ordering
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: OPP: Fix cleanup ordering Commit 173e02d67494 ("OPP: Initialize scope-based pointers inline") added initialization for all pointers. In some cases, the ordering was changed so that *opp_table was initialized after *opp. This also changes the order of the registered cleanup functions. When the cleanup happens, this can cause use-after-free errors when the last reference is released and the release function _opp_kref_release tries to access the already freed opp->opp_table. Initialize *opp_table before *opp again to fix this and ensure the correct cleanup order.
