CVE-2007-3739

Estado: ModificadaMedia (4.7)—

mm/mmap.c en el núcleo hugetlb, cuando se ejecuta en un sistema PowerP, no evita que la expansión de la pila entre en una página de memoria reservada por el núcleo, lo cual permite a usuarios locales provocar una denegación de servicio (OOPS) mediante vectores no especificados.
