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： 电源排序模块：修复 pwrseq_unit_new() 函数中的空指针解引用问题 当在 pwrseq_unit_setup_deps() 中内存分配失败时，会调用 pwrseq_unit_put() 来释放部分初始化的单元。然而，我们从未初始化 unit->list，而 pwrseq_unit_release() 会无条件地对其调用 list_del()。应在分配单元结构后，立即初始化 unit->list。

Vulnerability Title
power: sequencing: fix NULL-pointer dereference in pwrseq_unit_new()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: power: sequencing: fix NULL-pointer dereference in pwrseq_unit_new() If memory allocation fails in pwrseq_unit_setup_deps(), pwrseq_unit_put() is called to release the partially initialized unit. However, we've never initialized unit->list and pwrseq_unit_release() will unconditionally call list_del() on it. Initialize unit->list right after allocating the unit struct.
