## Overview

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

drm/amdkfd: fix potential kgd_mem UAFs

kgd_mem pointers returned by kfd_process_device_translate_handle are
only guaranteed to be valid while p->mutex is held. As soon as the mutex
is unlocked, another thread can free the BO.

## Affected

- `Linux >= 4a488a7ad71401169cecee75dc94bcce642e2c53 < 5045360f3bb62ccd4f87202e33489f71f8bbc3fc`
- `Linux >= 4a488a7ad71401169cecee75dc94bcce642e2c53 < 5ca14fb5552ac13a2402d306c0bd2379a71610ff`
- `Linux >= 4a488a7ad71401169cecee75dc94bcce642e2c53 < 9da050b0d9e04439d225a2ec3044af70cdfb3933`
- `Linux 3.19`
