| Description: | The validate_event function in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event. Vince Weaver discovered a flaw in the perf subsystem of the Linux kernel on ARM platforms. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash).
