A race condition vulnerability in the Linux kernel's perf subsystem was resolved. The issue occurs between perf_event_exit_task() and perf_pending_task() during the begin_new_exec() process. The flaw involves a timing conflict where the PF_EXITING flag is not set on the task, causing perf_sigtrap() to execute improperly and trigger a warning.
