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.

Security readout for executives and security teams

This flaw affects older Linux kernels before 3.8.9 on systems using the Performance Events subsystem. A local user could trigger a kernel fault and crash the system, causing denial of service. The bundle does not show remote exploitation or confirmed active exploitation. Exposure is most likely on legacy x86 Linux systems running kernels before 3.8.9, or vendor kernels lacking the referenced backport, with local user access available. Treat this as a legacy platform availability risk. It is not supported by the sources as remotely exploitable, but affected shared Linux systems could be crashed by local users. Prioritize patch confirmation on older production hosts. Mitigation focus: Upgrade to Linux kernel 3.8.9 or a vendor kernel containing the fix.; Review Red Hat and Mandriva advisories for distribution-specific fixed packages.; Prioritize shared servers where untrusted users can run local workloads..
