| Description: | 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. A use-after-free flaw was discovered in the Advanced Linux Sound Architecture (ALSA) control implementation of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash).
