Se detectó un problema en el kernel de Linux versiones anteriores a 4.20.2. Se presenta un acceso fuera de límites en la función build_audio_procunit en el archivo 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.

An update that solves 38 vulnerabilities and has 159 fixes is now available. The openSUSE Leap 15.0 kernel was updated to receive various security and bug fixes.
