USB: serial: io_ti: fix information leak in completion handler
commit 654b404f2a222f918af9b0cd18ad469d0c941a8e upstream.
Add missing sanity check to the bulk-in completion handler to avoid an
integer underflow that can be triggered by a malicious device.
This avoids leaking 128 kB of memory content from after the URB transfer
buffer to user space.
Fixes: 8c209e6782ca ("USB: make actual_length in struct urb field u32")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
