Descriptions

The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear allocated memory in some rare circumstances related to tmpfs, which might allow local users to read sensitive kernel data or cause a denial of service (crash).

La función shmem_getpage (mm/shmem.c) en el kernel de Linux versión 2.6.11 hasta 2.6.23 no borra de manera apropiada la memoria asignada en algunas circunstancias extrañas relacionadas con tmpfs, lo que podría permitir a los usuarios locales leer datos confidenciales del kernel o causar una denegación de servicio (bloqueo).
