CVE-2023-54202

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

drm/i915: fix race condition UAF in i915_perf_add_config_ioctl

Userspace can guess the id value and try to race oa_config object creation

with config remove, resulting in a use-after-free if we dereference the

object after unlocking the metrics_lock. For that reason, unlocking the

metrics_lock must be done after we are done dereferencing the object.

[tursulin: Manually added stable tag.]

(cherry picked from commit 49f6f6483b652108bcb73accd0204a464b922395)
