CWE-400  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The tty_open function in drivers/tty/tty_io.c in the Linux kernel before 3.1.1 mishandles a driver-lookup failure, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted access to a device file under the /dev/pts directory.
