Descriptions

Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors.

Xen 4.6.x y versiones anteriores no impone adecuadamente límites en órdenes de entrada de página para las suboperaciones (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange y posiblemente otra HYPERVISOR_memory_op, lo que permite a administradores ARM invitados del SO causar una denegación de servicio (consumo de CPU, reinicio de invitado o tiempo de watchdog excedido o reinicio host) y posiblemente tener otro impacto no especificado a través de vectores desconocidos.
