CVE-2014-4656: Integer Overflow
Last updated 24 July 2024
Other sources
Linux kernel built with the Advanced Linux Sound Architecture(ALSA) sound system support(CONFIGSND) is vulnerable to an integer overflow flaw. It could occur when user space application removes or adds new controls.
A user/application could use this flaw to crash the system kernel resulting in DoS.

— Red Hat
Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the sndctladd function and (2) numid values in the sndctlremovenumidconflict function.
