Descriptions

The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors.

La función guest_physmap_mark_populate_on_demand en Xen v4.2 y anteriores no desbloquea correctamente los GFNs al comprobar si están en uso, lo que permite causar una denegación de servicio (caída del HVM)a los administradores de HVM invitados locales a través de vectores no especificados.
