CVE-2022-48950

CVE-2022-48950 affects the Linux kernel: perf_pending_task() UaF could run after the event is freed. The root cause involves two situations: (1) task_work already queued before destroying the event; (2) destroying the event queues task_work. The documented fix is to extend the perf_event lifetime...
