Description Agostino Sarubbo gentoo-dev 2013-11-25 19:49:45 UTC
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.

Upstream fix:
