## Overview

A flaw was found in the Linux kernel's iwlwifi driver. A local user can trigger an unintended kernel warning by configuring Wake on Wireless LAN (WoWLAN) and suspending the system while disconnected from a network. On systems configured to panic or halt on kernel warnings, this flaw may lead to a system crash and a denial of service (DoS).
