Descriptions

The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel before 3.18-rc2 lacks intended decoder-table flags for certain RIP-relative instructions, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a crafted application.

El decodificador de instrucciones en arch/x86/kvm/emulate.c en el subsistema KVM en el kernel de Linux anterior a 3.18-rc2 le falta indicadores de las tablas del decodificador para ciertas instrucciones relacionados con RIP, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (referencia a puntero nulo y caída del sistema operativo anfitrión) a través de una aplicación manipulada.
