CVE-2014-4654
Publication date 3 July 2014
Last updated 24 July 2024
Ubuntu priority
The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call.
From the Ubuntu Security Team
A authorization bug was discovered with the snd_ctl_elem_add function of the Advanced Linux Sound Architecture (ALSA) in the Linux kernel. A local user could exploit his bug to cause a denial of service (remove kernel controls).
