Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper access control for some Intel(R) PROSet/Wireless WiFi and Killer(TM) WiFi products may allow a privileged user to potentially enable information disclosure via local access.

Recommended fix High confidence

Intel PROSet/Wireless firmware >= 22.120; Killer WiFi firmware >= 3.1122.1105

  1. 1. Identify the exact wireless adapter model in the system using Device Manager (Windows) or lspci / iwconfig (Linux)
  2. 2. Visit the Intel support website or the system manufacturer's support page to download the correct firmware update
  3. 3. For Intel PROSet/Wireless adapters: Download firmware version 22.120 or later from Intel's support site or system OEM
  4. 4. For Killer wireless adapters: Download firmware version 3.1122.1105 or later from Razer (Killer) support site
  5. 5. Follow the vendor-provided instructions to install the firmware update - this typically requires running the Intel PROSet/Wireless software utility or Killer Software utility
  6. 6. Restart the system after the firmware update completes to ensure the new firmware is loaded
  7. 7. Verify the firmware version has been updated by checking the wireless adapter properties in Device Manager or using system information tools
Caveat Firmware update may briefly interrupt wireless connectivity during installation; ensure stable power during update to avoid rendering the wireless adapter inoperable
