  "details": "In the Linux kernel, the following vulnerability has been resolved:  perf: Fix race between perf_event_exit_task() and perf_pending_task()  A race condition exists between perf_event_exit_task() and perf_pending_task() during begin_new_exec().  During begin_new_exec(), perf_event_exit_task() may be called, and the PF_EXITING flag is not set on task. So perf_sigtrap() continues to execute and triggers WARN_ON_ONCE(event-\u003ectx-\u003etask != current).  Since both task exit and exec paths can call perf_event_exit_task() which sets ctx-\u003etask to TASK_TOMBSTONE, fix this by explicitly checking if event-\u003ectx-\u003etask equals TASK_TOMBSTONE and dropping the redundant PF_EXITING check.",
