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
Exposure of Sensitive Information to an Unauthorized Actor in firmware 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 authenticated user to potentially enable information disclosure via local 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 · high confidence

Information disclosure vulnerability in Intel PROSet/Wireless Wi-Fi and Killer Wi-Fi firmware allows an authenticated local user to potentially access sensitive information via local access to the affected system.

MitigationApply vendor-supplied firmware updates for affected Intel PROSet/Wireless and Killer Wi-Fi adapters; verify patch deployment across all affected endpoints.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Wi-Fi adapter model
    Open Device Manager, expand Network adapters, and look for Intel PROSet/Wireless or Killer Wi-Fi adapter (e.g., Intel Wi-Fi 6 AX200, Intel AC 8260, etc.)
    Affected if The adapter model matches one of the affected products: AC 8260, AC 8265, AC 9260, AC 9560, Wi-Fi 6 AX200, Wi-Fi 6 AX201, Wi-Fi 6 AX210, or Proset AC 3165
  2. Retrieve the current firmware version
    Use Intel PROSet Wireless diagnostic tool, or run 'netsh wlan show drivers' in Command Prompt, or check firmware version via Device Manager under the adapter properties Details tab looking for 'Firmware Version'
    Affected if The displayed firmware version is readable and can be compared against the affected ranges
  3. Compare firmware version for AC 8260/8265
    If adapter is AC 8260 or AC 8265, check if firmware version is less than 11.8.90
    Affected if Firmware version < 11.8.90 for AC 8260 or AC 8265
  4. Compare firmware version for AC 9260/9560
    If adapter is AC 9260 or AC 9560, check if firmware version is less than 12.0.85
    Affected if Firmware version < 12.0.85 for AC 9260 or AC 9560
  5. Compare firmware version for Wi-Fi 6 AX200/AX201/AX210
    If adapter is AX200, AX201, or AX210: check if version < 12.0.85 OR between 14.0.0 and 14.1.60 (exclusive) OR between 15.0.0 and 15.0.35 (exclusive)
    Affected if Firmware version falls into any of the vulnerable ranges: < 12.0.85, >= 14.0.0 and < 14.1.60, or >= 15.0.0 and < 15.0.35 for AX200/AX201/AX210
  6. Compare firmware version for AC 3165
    If adapter is Proset AC 3165, check if firmware version is less than 22.60
    Affected if Firmware version < 22.60 for AC 3165

The system is affected if an Intel Wi-Fi adapter from the list is installed with a firmware version matching any of the vulnerable version ranges provided.

Fixed in 11.8.9012.0.8514.1.60
Interim mitigation

Apply vendor-supplied firmware updates for affected Intel PROSet/Wireless and Killer Wi-Fi adapters; verify patch deployment across all affected endpoints.

Recommended fix High confidence

Upgrade to firmware version 11.8.90 or later (for 8260/8265), 12.0.85 or later (for 9260/9560 and early AX200/AX201/AX210), 14.1.60 or later, 15.0.35 or later (for AX200/AX201/AX210), or 22.60 or later (for 3165) depending on the specific adapter model

  1. Identify the exact wireless adapter model by checking Device Manager or system documentation
  2. Determine the current firmware version installed on the wireless adapter
  3. Based on the adapter model, upgrade to the minimum fixed version: For Intel Wi-Fi 6 AX200/AX201/AX210: upgrade to 12.0.85, 14.1.60, or 15.0.35 or later | For Intel AC 8260/8265: upgrade to 11.8.90 or later | For Intel AC 9260/9560: upgrade to 12.0.85 or later | For Intel PROSet Wireless 3165: upgrade to 22.60 or later
  4. Download the appropriate firmware update from the Intel Support website (downloadcenter.intel.com) or use the Intel PROSet/Wireless Software update utility
  5. Apply the firmware update following Intel's standard update procedure, which typically requires administrator privileges and may involve a system restart
Caveat Firmware updates may temporarily interrupt wireless connectivity; ensure wired backup or save work before applying; some older systems may have limited update path options
