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 Validation of Specified Index, Position, or Offset in Input in software for some Intel(R) PROSet/Wireless Wi-Fi in multiple operating systems and some Killer(TM) Wi-Fi in Windows 10 and 11 may allow an unauthenticated user to potentially enable denial of service via adjacent access.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-20

The application accepts input without confirming it is well-formed or within expected bounds, so malformed data can push the program into states its author never anticipated. Attackers probe these gaps to trigger crashes, bypass logic, or feed tainted values into more dangerous operations downstream. Remediating it well means validating and normalising every input at the boundary against a strict allow-list — not merely filtering known-bad values.

Recommended fix High confidence

Firmware version >= 11.8.90 (8260/8265), >= 12.0.85 (9260/9560), >= 15.0.35 (Ax200/Ax201/Ax210), >= 22.60 (3165)

  1. 1. Identify the exact Intel Wi-Fi adapter model in the affected system (e.g., AX200, AX201, AX210, 8260, 8265, 9260, 9560, or 3165)
  2. 2. Visit the Intel Support website or the vendor advisory at https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00539.html
  3. 3. Locate the firmware download for the specific adapter model
  4. 4. For Amt Ac 8260/8265: upgrade to firmware version 11.8.90 or later
  5. 5. For Amt Ac 9260/9560: upgrade to firmware version 12.0.85 or later
  6. 6. For Amt WiFi 6 Ax200/Ax201/Ax210: upgrade to firmware version 15.0.35 or later (or 14.1.60 for the 14.x branch)
  7. 7. For Proset Ac 3165: upgrade to firmware version 22.60 or later
  8. 8. Apply the firmware update using Intel's recommended update method (Intel PROSet Wireless Software, Intel Driver & Support Assistant, or vendor-specific tools)
Caveat Firmware updates may require Wi-Fi driver updates; ensure compatible drivers are installed before flashing firmware to avoid compatibility issues
