The driver flaw can be triggered when an affected device is within radio range of a malicious device. As long as the Wi-Fi is turned on, it requires no interaction on the part of the end user. The malicious device exploits the vulnerability by using a power-saving feature known as a Notice of Absence. The flaw dates back to version 3.10.1 of the Linux kernel.
