Description

A use-after-free flaw was found in the Linux kernel’s performance events functionality. A user triggers a race condition in setting up performance monitoring between the leading PERF_TYPE_TRACEPOINT and sub PERF_EVENT_HARDWARE plus the PERF_EVENT_SOFTWARE using the perf_event_open() function with these three types. This flaw allows a local user to crash the system.
