Descriptions

The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory.

La función guest_walk_tables en arch/x86/mm/guest_walk en Xen 4.6.x y versiones anteriores no maneja adecuadamente el bit de entrada a la tabla de página Page Size (PS) en los niveles de tabla de página L4 y L3, lo que podría permitir a usuarios locales huéspedes del sistema operativo obtener privilegios a través de un mapa de memoria manipulado.
