What it actually does

The software fails to enforce expected protocol conventions, allowing an unauthenticated adjacent attacker to trigger a denial-of-service condition that disrupts Wi-Fi functionality.

Why it matters to the business

Affected systems may experience intermittent or prolonged loss of wireless connectivity, leading to operational downtime and reduced productivity until the issue is resolved.

How an attack unfolds

An attacker positioned on the same wireless network sends crafted frames that exploit the convention violation, causing the driver or service to enter a failure state without authentication.

How to fix it

Upgrade Intel PROSet/Wireless and Intel Killer Wi-Fi software to the current release that enforces expected conventions; apply vendor patches as they become available and verify the installed version meets or exceeds the fixed release.

How to confirm the fix worked

Confirm the software version is at or above the patched release through the vendor management console or driver properties; test that adjacent unauthenticated traffic no longer produces denial-of-service behavior.

Typical attack path

  1. Obtain adjacent wireless network access
  2. Transmit non-conforming Wi-Fi management or data frames
  3. Trigger software instability resulting in service denial

How to detect it

Review wireless driver and system logs for repeated service crashes or unexpected disconnections correlated with unknown adjacent devices; monitor for anomalous management frame activity on the wireless interface.

What your security team should do

  • Prioritize deployment of the latest driver versions across all endpoints using the affected software
  • Restrict adjacent network exposure where feasible until updates are applied
  • Include the affected wireless components in regular patch and configuration audits

The record

Insufficient adherence to expected conventions for some Intel(R) PROSet/Wireless and Intel(R) Killer(TM) Wi-Fi software before version 22.240 may allow an unauthenticated user to potentially enable denial of service via adjacent access.
