Descriptions

The vmsplice_to_user function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which might allow local users to access arbitrary kernel memory locations.

La función vmsplice_to_user en fs/splice.c del núcleo de Linux 2.6.22 hasta 2.6.24 no valida ciertos punteros en el espacio antes referenciados, lo cual permite a usuarios locales acceder a localizaciones de memoria del núcleo de su elección.
