Descriptions

The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511.

La función uio_mmap_physical en drivers/uio/uio.c del kernel de Linux anterior a la versión 3.12 no valida el tamaño de un bloque de memoria, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) o posiblemente obtener privilegios a través de operaciones mmap manipuladas, una vulnerabilidad diferente a CVE-2013-4511.
