Descriptions

Certain MMU virtualization operations in Xen 4.2.x through 4.4.x before the xsa97-hap patch, when using Hardware Assisted Paging (HAP), are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5149.

Ciertas operaciones de la virtualización MMU en Xen 4.2.x hasta 4.4.x anterior al patch xsa97-hap, cuando utiliza Hardware Assisted Paging (HAP), no son preferentes, lo que permite a huéspedes locales HVM causar una denegación de servicio (consumo de vcpu) mediante la invocación de estas operaciones, las cuales procesan cada página asignada a un huésped, una vulnerabilidad diferente a CVE-2014-5149.
