NVD

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

drm/amdgpu: fix AMDGPU INFO READ MMR REG

There were multiple issues in that code.

First of all the order between the reset semaphore and the mm lock was wrong (e.g. copy to user) was called while holding the lock.

Then we allocated memory while holding the reset semaphore which is also a pretty big bug and can deadlock.

Then we used down read trylock() instead of waiting for the reset to finish.

(cherry picked from commit 361b6e6b303d4b691f6c5974d3eaab67ca6dd90e)
