Description Prasad Pandit 2014-06-26 08:23:14 UTC 
Linux kernel built with the Advanced Linux Sound Architecture(ALSA) sound
system support(CONFIG_SND) is vulnerable to a use after free flaw. It
could occur when user space application removes arbitrary controls.

A user/application could use this flaw to crash the system kernel resulting in
DoS.
