In the Linux kernel, the following vulnerability has been resolved:

dm: fix resume-vs-remove race

If the user issues the resume ioctl and the remove ioctl at the same

time, it may be possible that the device is resumed after it is suspended

in __dm_destroy. The result is that the table is destroyed without

calling the postsuspend method.

Dm targets expect that they may be removed only after the postsuspend

method method was called. If we break this expectation, it can cause

misbehavior in various targets. For example - in the dm-integrity target,

the reboot notifier is not unregistered, leading to use-after-free.

Fix this bug by refusing to resume if the device is being destroyed. (NVD)
