kernel: out-of-bounds in function build_audio_procunit in sound/usb/mixer.c
An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.
An out-of-bounds flaw was found in the ALSA usb-audio subsystem in the Linux kernel. An array boundary check was needed to restrict the array size; failing this can cause an out-of-bound access problem. Data confidentiality and integrity, as well as system availability, are all threats with this vulnerability.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
