优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在 Linux 内核中，已修复以下漏洞： remoteproc：防止崩溃处理与 rproc_del() 发生竞态 和 之间缺乏同步机制。因此，当崩溃处理工作被调度甚至正在执行时，驱动可能被移除，从而导致“释放后使用”（use-after-free）问题。 为避免此问题，必须在移除流程继续之前，取消并同步已调度的工作项。 为确保不与崩溃报告过程发生竞态（该过程可能会调度新的工作项），引入了一个“正在删除”标志。这与之前为确保“start”不与 竞态而引入的 状态类似；但现有机制无法直接复用，因为在原子上下文中调用 是

Vulnerability Title
remoteproc: Prevent crash handling to race with rproc_del()
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: Prevent crash handling to race with rproc_del()
There's no synchronization between rproc_crash_handler_work() and
rproc_del(), as such it's possible for a driver to be removed while
crash-handler work is scheduled, or even executing - resulting in
use-after-free issues.
To avoid this the scheduled work need to be cancelled and synchronized
against before the removal proceeds.
In order to ensure that this doesn't race with the reporting, and
thereby scheduling new work, a "deleting" flag is introduced. This is
similar to the RPROC_DELETE state that was introduced to ensure that
"start" didn't race with rproc_del(), but the existing mechanism can not
be used as it's valid to call rproc_report_crash() in atomic context -
and the "state" is protected by a mutex.
In the event that work is cancelled the pm_stay_awake() is left
unbalanced and need to be unrolled.
The blocking and cancelling of crash-handler work prior to the actual
rproc_shutdown() call does have the explicit side-effect that crashes
resulting from the shutdown process will not enter the crash-handling
path, and as such will not generate devcoredumps etc. Due to the
existing mutual exclusion between these code paths there's no concrete
reduction in functionality, but further work would be needed to handle
this case.
