* USB: serial: safe_serial: fix information leak in completion handlerJohan Hovold2017-06-171-0/+5
| | | | | | | | | | | | | | commit 8c76d7cd520ebffc1ea9ea0850d87a224a50c7f2 upstream. Add missing sanity check to the bulk-in completion handler to avoid an integer underflow that could be triggered by a malicious device. This avoids leaking up to 56 bytes from after the URB transfer buffer to user space.
