** Description changed: - The valid mask for both offcore_response_0 and offcore_response_1 was - wrong for SNB/SNB-EP, IVB/IVB-EP. It was possible to write to reserved - bit and cause a GP fault crashing the kernel. This patch fixes the - problem by correctly marking the reserved bits in the valid mask for all - the processors mentioned above. + 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. Break-Fix: - f1923820c447e986a9da0fc6bf60c1dccdf0408e
