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 snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function.
AnalysisAI
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. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity.
Technical ContextAI
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. 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 snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function. Affected products include: Linux Linux Kernel, Suse Linux Enterprise Server, Canonical Ubuntu Linux, Redhat Enterprise Linux Desktop, Redhat Enterprise Linux Eus. Version information: before 3.15.2.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate arithmetic operations, use safe integer libraries, check bounds before allocation.
