Description: | 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. An information leak was discovered in the control implemenation of the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory.
