Description
Description
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)
