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 input validation for some Intel(R) PROSet/Wireless WiFi, Intel vPro(R) CSME WiFi and Killer(TM) WiFi products may allow unauthenticated user to potentially enable denial of service 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 · moderate confidence

Improper input validation in Intel PROSet/Wireless WiFi, Intel vPro CSME WiFi, and Killer WiFi drivers allows an unauthenticated local attacker to trigger a denial of service condition. The vulnerability stems from insufficient validation of input data processed by the WiFi software components.

MitigationApply vendor-supplied patches or firmware updates for affected Intel and Killer WiFi products. Until patches are available, limit physical and local access to systems with vulnerable WiFi components.

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 installed Intel PROSet/Wireless WiFi software version
    Open Windows Control Panel > Programs and Features, or use 'wmic product get name,version' to list installed Intel WiFi software
    Affected if Version is present and less than 22.140
  2. Identify installed Killer WiFi software version
    Open Windows Control Panel > Programs and Features, or check the Killer Support Center app for software version information
    Affected if Version is present and less than 3.1122.3158
  3. Identify WiFi adapter firmware version
    Open Device Manager > Network Adapters > right-click WiFi adapter > Properties > Driver tab, or use 'netsh wlan show interfaces' to display firmware details
    Affected if Adapter model is one of: Killer WiFi 6 Ax1650, Killer WiFi 6e Ax1675, Killer WiFi 6e Ax1690, WiFi 6 Ax200, or WiFi 6 Ax201 (all firmware versions affected)
  4. Check Intel UEFI WiFi Driver version
    Open Device Manager > System Devices > Intel UEFI WiFi Driver (if present) and check driver version in Properties, or check BIOS/UEFI firmware version if the driver is bundled
    Affected if Driver version is present and less than 2.2.14.22176

You are affected if any Intel PROSet/Wireless WiFi software is below 22.140, any Killer WiFi software is below 3.1122.3158, the Intel UEFI WiFi Driver is below 2.2.14.22176, or your adapter uses any firmware version on the Killer WiFi 6 Ax1650/6e Ax1675/6e Ax1690 or WiFi 6 Ax200/Ax201 models.

Interim mitigation

Apply vendor-supplied patches or firmware updates for affected Intel and Killer WiFi products. Until patches are available, limit physical and local access to systems with vulnerable WiFi components.

Recommended fix High confidence

Killer Wifi Software: 3.1122.3158 | Intel PROSet/Wireless WiFi: 22.140 | UEFI WiFi Driver: 2.2.14.22176 | Respective firmware updates from Intel/system manufacturer

  1. Identify the specific Killer or Intel WiFi product and current version installed on the system
  2. For Killer Wifi Software: Navigate to the Killer Support website or use the Killer Intelligence Center to check for updates and upgrade to version 3.1122.3158 or later
  3. For Intel PROSet/Wireless WiFi: Use Intel Driver & Support Assistant or manually download from Intel support to upgrade to version 22.140 or later
  4. For UEFI WiFi Driver: Obtain the updated driver version 2.2.14.22176 or later from the system manufacturer or Intel
  5. For firmware versions listed as 'all versions' affected (Ax1650, Ax1675, Ax1690, Ax200, Ax201): Contact the system manufacturer or Intel for firmware updates that address the vulnerability
  6. Verify the update was successful by checking the installed version number after reboot
Caveat Firmware updates for WiFi adapters may require system downtime and should be tested in a non-production environment first; some enterprise deployments may require IT approval
