Descriptions

arch/x86/kernel/cpu/perf_event_intel.c in the Linux kernel before 3.8.9, when the Performance Events Subsystem is enabled, specifies an incorrect bitmask, which allows local users to cause a denial of service (general protection fault and system crash) by attempting to set a reserved bit.

arch/x86/kernel/cpu/perf_event_intel.c en Linux kernel hasta v3.8.9 cuando Performance Events Subsystem esta habilitado, especifica una máscara de bits correctos, lo que permite a usuarios locales provocar una denegación de servicio (error de protección general y el bloqueo del sistema) al tratar de establecer un bit reservado.
