CVE-2023-54202

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/i915: fix race condition UAF in i915_perf_add_config_ioctl<br /> <br /> Userspace can guess the id value and try to race oa_config object creation<br /> with config remove, resulting in a use-after-free if we dereference the<br /> object after unlocking the metrics_lock. For that reason, unlocking the<br /> metrics_lock must be done after we are done dereferencing the object.<br /> <br /> [tursulin: Manually added stable tag.]<br /> (cherry picked from commit 49f6f6483b652108bcb73accd0204a464b922395)
