The Centos security team deemed this advisory irrelevant for Centos:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-debug-core package and not the kernel-rt-64k-debug-core package as distributed by Centos.
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)
