Descriptions

The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptible, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm).

La hiperllamada XEN_DOMCTL_memory_mapping en Xen 3.2.x hasta la versión 4.5.x, cuando utiliza un dispositivo de paso PCI, no es predecible, lo que podría permitir a usuarios locales del dominio HVM x86 provocar una denegación de servicio (consumo CPU del host) a través de una petición manipulada para el modelo del dispositivo (qemu-dm).

Multiple vulnerabilities have been found in Xen, the worst of which can allow remote attackers to cause a Denial of Service condition. Versions less than 4.4.2-r1 are affected.
