CVE-2023-54202

CVE-2023-54202 affects the Linux kernel DRM/I915 component (i915_perf_add_config_ioctl). The issue is a race leading to a use-after-free when an oa_config object is created while config removal races with metrics_lock, if the code dereferences the object after unlocking metrics_lock. The vulnerab...
