The us122l driver creates URBs per the fixed endpoints, and this may end up with URBs with inconsistent pipes when a fuzzer or a malicious program deals with the manipulated endpoints. It ends up with a kernel warning like: usb 1-1: BOGUS urb xfer, pipe 0 != type 3 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 24 at drivers/usb/core/urb.c:471 usb_submit_urb+0x113e/0x1400 Call Trace: usb_stream_start+0x48a/0x9f0 sound/usb/usx2y/usb_stream.c:690 us122l_start+0x116/0x290 sound/usb/usx2y/us122l.c:365 us122l_create_card sound/usb/usx2y/us122l.c:502 us122l_usb_probe sound/usb/usx2y/us122l.c:588 .... For avoiding the bad access, this patch adds a few sanity checks of the validity of created URBs like previous similar fixes using the new usb_urb_ep_type_check() helper function.
