      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nperf: Fix race between perf_event_exit_task() and perf_pending_task()\n\nA race condition exists between perf_event_exit_task() and\nperf_pending_task() during begin_new_exec().\n\nDuring begin_new_exec(), perf_event_exit_task() may be called, and the\nPF_EXITING flag is not set on task. So perf_sigtrap() continues to execute\nand triggers WARN_ON_ONCE(event->ctx->task != current).\n\nSince both task exit and exec paths can call perf_event_exit_task() which\nsets ctx->task to TASK_TOMBSTONE, fix this by explicitly checking if\nevent->ctx->task equals TASK_TOMBSTONE and dropping the redundant\nPF_EXITING check.",
