USB: serial: io_ti: fix information leak in completion handler 2017-04-18T05:55:50+00:00 Johan Hovold johan@kernel.org 2017-03-06T16:36:40+00:00 1f5371cc84232fc5b3140713d681b35641c56c17 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.
