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.]
