CVE-2023-54202

תיאור (מקור, אנגלית)

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)
