On October 29, 2021, D-Link became aware of a number of potential MediaTek WiFi vulnerabilities involving Wi-Fi WPS/IEEE-1905 called BadMesher & Authentication Flooding. As soon as D-Link was made aware of the reported security issues, we had promptly started our investigation and began developing security patches.

D-Link takes the issues of network security and user privacy very seriously. We have a dedicated task force and product management team on call to address evolving security issues and implement appropriate security measures.
