CVE-2014-3611

Estado: ModificadaMedia (4.7)—

Condición de carrera en la función __kvm_migrate_pit_timer en arch/x86/kvm/i8254.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de la emulación PIT incorrecta.
