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
Insecure inherited permissions in the Intel(R) PROSet/Wireless WiFi software installer for Windows 10 before version 22.40 may allow an authenticated user to potentially enable escalation of privilege 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

Insecure inherited permissions in the Intel(R) PROSet/Wireless WiFi software installer for Windows 10 prior to version 22.40 allows an authenticated local user to potentially escalate privileges. The vulnerability stems from improper permission inheritance in the installer component, enabling a local attacker to gain elevated access.

MitigationUpdate Intel PROSet/Wireless WiFi software to version 22.40 or later to remediate the insecure permissions issue.

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. Confirm Intel PROSet/Wireless WiFi software is installed
    Open Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed programs. Look for entries containing 'Intel PROSet' or 'Intel Wireless' in the name.
    Affected if Intel PROSet/Wireless WiFi software is present on the system
  2. Check the installed Intel PROSet/Wireless WiFi software version
    Run 'Get-ItemProperty "HKLM:\SOFTWARE\Intel\PlugPlay\Components\*" -ErrorAction SilentlyContinue | Where-Object {$_.DisplayName -like "*WiFi*"} | Select-Object DisplayName, ComponentVersion' in PowerShell, or right-click the WiFi adapter in Device Manager > Properties > Driver tab to view the driver version.
    Affected if The displayed version is earlier than 22.40
  3. Identify the WiFi adapter firmware version
    Open Device Manager > Network adapters > Intel WiFi adapter > Properties > Advanced tab. Look for 'Firmware Version' or similar field. Alternatively, run 'netsh wlan show drivers' to see driver details.
    Affected if The adapter is one of: Intel Ax210, Ax201, Ax200, Ac 9560, Ac 9462, Ac 9461, Ac 9260, or Ac 8265 with firmware version prior to 22.40
  4. Verify the vulnerability condition is met
    Confirm that Intel PROSet/Wireless WiFi software version is less than 22.40 AND the system has an affected Intel WiFi adapter model listed in the CVE. Check Program Files or Program Files (x86) for Intel folders and review installer component permissions if accessible.
    Affected if Both conditions are true: software version < 22.40 AND affected WiFi adapter firmware is present

A system is affected if Intel PROSet/Wireless WiFi software version is below 22.40 and the system uses one of the affected Intel WiFi adapters (Ax210, Ax201, Ax200, Ac 9560, Ac 9462, Ac 9461, Ac 9260, or Ac 8265) with firmware versions prior to 22.40.
