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
Integer overflow in WebNN in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)

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.

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 Google Chrome is installed
    Locate Chrome executable: On Windows check C:\Program Files\Google\Chrome\Application\chrome.exe, on macOS check /Applications/Google Chrome.app, or on Linux check /usr/bin/google-chrome
    Affected if Google Chrome browser is present on the system
  2. Determine installed Chrome version
    Open chrome://version in the Chrome address bar or run 'google-chrome --version' from command line (Linux/macOS) or check the executable properties on Windows
    Affected if The displayed version number is less than 150.0.7871.46
  3. Verify WebNN API is enabled
    Navigate to chrome://flags/#webnn-enabled in the Chrome address bar and check the WebNN flag status
    Affected if The WebNN flag is set to Enabled, making the vulnerable WebNN API component active in the browser

The system is affected if Google Chrome is installed with a version below 150.0.7871.46 AND the WebNN feature flag is enabled, as the integer overflow vulnerability exists only in the WebNN API component.
