CVE-2010-0730

Estado: ModificadaBaja (2.6)—

El decodificador de instrucciones MMIO en el hipervisor Xen en el kernel Linux 2.6.18 en Red Hat Enterprise Linux (RHEL) 5 permite a los usuarios de los sistemas operativos huesped causar una denegación de servicio (cuelgue de sistema operativo huesped de 32-bit) a través de vectores que provocan una emulación de la instrucción sin especificar.
