CVE request: Linux kernel: USB: io_ti: NULL pointer dereference
From: P J P <ppandit () redhat com>
Date: Wed, 27 Feb 2013 19:39:50 +0530 (IST)


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 corresponding /dev/ttyUSB? file is in use.

An unprivileged user could use this flaw to crash the system, resulting DoS.

Upstream fix:
 -> https://git.kernel.org/linus/1ee0a224bc9aad1de496c795f96bc6ba2c394811
