Wi-Fi Alliance® security update – May 11, 2021

May 11, 2021

Austin, TX – May 11, 2021 – Wi-Fi Alliance® provides trusted security to billions of Wi-Fi® devices, and regularly updates Wi-Fi CERTIFIED™ requirements to address wireless security and privacy challenges as the threat landscape evolves.

Security researchers identified vulnerabilities in the frame aggregation functionality of some Wi-Fi devices. There is no evidence of the vulnerabilities being used against Wi-Fi users maliciously, and these issues are mitigated through routine device updates that enable detection of suspect transmissions or improve adherence to recommended security implementation practices. Wi-Fi Alliance has taken immediate steps to ensure users can remain confident in the strong security protections provided by Wi-Fi.

  • Wi-Fi CERTIFIED now includes additional testing within our global certification lab network to encourage greater adoption of recommended practices
  • Wi-Fi Alliance is broadly communicating implementation guidance to device vendors and the broader ecosystem community
  • Many Wi-Fi Alliance members affected by the issue have already started deploying updates to user devices

As always, Wi-Fi users should ensure they have installed the latest recommended updates from device manufacturers.

As with any technology, robust security research that pre-emptively identifies potential vulnerabilities is critical to maintaining strong protections. Wi-Fi Alliance thanks Mathy Vanhoef (New York University Abu Dhabi) for discovering and responsibly reporting this issue, allowing industry to proactively prepare updates. Wi-Fi Alliance also thanks the Industry Consortium for Advancement of Security on the Internet (ICASI) for their strong partnership and collaboration.
