NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.
