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.

Security readout for executives and security teams

This is an old Linux kernel ALSA sound-control bug. A local user with access to ALSA control devices could trigger integer overflows and crash or disrupt the system. It is not a remote compromise based on the provided sources. Exposure is most likely on unpatched Linux systems or vendor kernels missing the upstream/vendor backports, especially multi-user systems where untrusted users can access /dev/snd/controlC* devices. Treat this as a targeted hygiene issue, not an internet-scale emergency. Prioritize shared Linux systems and older embedded or Android-derived builds where local users or workloads can reach ALSA controls. Mitigation focus: Update Linux kernels using vendor advisories or a release containing the upstream fixes.; Verify whether vendor-maintained kernels backported the relevant ALSA fixes.; Restrict untrusted local access to /dev/snd/controlC* where operationally feasible..
