Summary

Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function.
