From ${URL} :

Linux kernel built with a USB over WiFi Host Controller(CONFIG_USB_WPAN_HCD)
driver support is vulnerable to a buffer overflow flaw. It could occur while
writing to the device file.

A user/program able to write to the device file could use this flaw to potentially further escalate 
privileges on a system.

CVE-2013-4513 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4513):
  Buffer overflow in the oz_cdev_write function in
  drivers/staging/ozwpan/ozcdev.c in the Linux kernel before 3.12 allows local
  users to cause a denial of service or possibly have unspecified other impact
  via a crafted write operation.
