Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Bound MIDI 2.0 endpoint descriptor scans
The USB MIDI 2.0 endpoint parser has the same descriptor walking
pattern as the legacy MIDI parser. It validates bLength against
bNumGrpTrmBlock before reading baAssoGrpTrmBlkID[], but not against the
remaining bytes in the endpoint-extra scan.
A malformed device can therefore make later baAssoGrpTrmBlkID[] reads
consume bytes past the walked descriptor.
Reject zero-length and overlong descriptors while walking endpoint
extras.
