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，以下漏洞已得到解决： 平台/Chrome：cros_ec_debugfs：注销 panic 通知器 函数将 注册到 EC panic 通知器链中。在设备移除路径中，代码会拆毁 debugfs 和控制台日志，但并未注销该通知器。这导致后续的 panic 通知可能会回调到已被移除的实例，并触发访问已释放数据的后台工作队列任务，从而引发潜在问题。 修复方法：在拆毁 debugfs 和控制台日志状态之前，先注销 panic 通知器。 该问题由静态分析工具发现。

Vulnerability Title
platform/chrome: cros_ec_debugfs: Unregister panic notifier
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_debugfs: Unregister panic notifier
cros_ec_debugfs_probe() registers notifier_panic with the EC panic
notifier chain. The remove path tears down debugfs and the console log,
but leaves the notifier registered. A later panic notification can call
back into the removed instance and queue work that accesses released
data.
Unregister the panic notifier before tearing down the debugfs and
console log state.
This issue was found by a static analysis tool.
