Descriptions

The do_hvm_op function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x86_32 platform does not prevent HVM_PARAM_NESTEDHVM (aka nested virtualization) operations, which allows guest OS users to cause a denial of service (long-duration page mappings and host OS crash) by leveraging administrative access to an HVM guest in a domain with a large number of VCPUs.

La función en xen/arch/x86/hvm/hvm.c en Xen v4.2.x en la plataforma x86_32 no previenen operaciones HVM_PARAM_NESTEDHVM (también conocido como virtualización anidada) lo que permite a usuarios invitados del SO generar una denegación de servicio (asignaciones de página de larga duración y caída del host OS) al aprovechar el acceso administrativo a un huésped HVM en un dominio con un gran número de CPU virtuales.
