Descriptions

Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock.

Xen v4.1.1 y anteriores permite causar una denegación de servicio (consumo de CPU y bloqueo de Xen) a los kernels de sistemas operativos huesped que controlan dispositivos PCI[E] a través de muchas peticiones DMA modificadas que son denegadas por la IOMMU, lo que desencadena un bloqueo activo.
