Descriptions

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.

Desbordamiento de búfer en virt/KVM/irq_comm.c en el subsistema de KVM en el kernel de Linux antes de v3.2.24 que permite a usuarios locales provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de vectores relacionados con las interrupciones señalizadas por mensajes (MSI), entradas iRQ y un control incorrecto de la función setup_routing_entry antes de invocar la función kvm_set_irq.
