Description Prasad Pandit 2013-02-27 14:02:44 UTC 
Linux kernel built with Edgeport USB serial converter driver io_ti,
is vulnerable to a NULL pointer dereference flaw. It happens if the device is
disconnected while in use.

A user able to read/write from /dev/ttyUSB? file could use this flaw to crash the system, resulting in DoS.
