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： power: sequencing: 修复 pwrseq_device_register() 中的空指针解引用 如果 函数中调用 失败，代码会在初始化 之前跳转到 标签处。此时， 会无条件地尝试遍历 列表，进而解引用一个无效指针，导致空指针解引用错误。为解决此问题，将 的调用移至列表头（list head）初始化之后执行。

Vulnerability Title
power: sequencing: fix NULL-pointer dereference in pwrseq_device_register()
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_device_register() If dev_set_name() fails in pwrseq_device_register(), we jump to the err_put_pwrseq label before initializing pwrseq->targets. pwrseq_release() will try to iterate over targets unconditionally and subsequently dereference an invalid pointer. Move the call to dev_set_name() after the list head is initialized.
