ALSA: usb-audio: Bound MIDI endpoint descriptor scans
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI endpoint descriptor scans snd_usbmidi_get_ms_info() validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID[], but the descriptor walker can still return a class-specific endpoint descriptor whose bLength exceeds the remaining bytes in the endpoint-extra scan. That leaves later flexible-array reads bounded by bLength, but not by the remaining bytes in the endpoint-extra scan. Stop walking when bLength is zero or extends past the remaining endpoint-extra scan.
