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.
