Descriptions

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

Condición de carrera en la funcionalidad del manejador de tlv en la función snd_ctl_elem_user_tlv en sound/core/control.c en la implementación del control ALSA en el kernel de Linux anterior a 3.15.2 permite a usuarios locales obtener información sensible de la memoria del kernel mediante el aprovechamiento del acceso a /dev/snd/controlCX

An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space.
