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
Type confusion in V8 in Google Chrome prior to 138.0.7204.96 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page. (Chromium security severity: High)

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

Type confusion vulnerability in Chrome's V8 JavaScript engine allows a remote attacker to perform arbitrary read/write operations via a crafted HTML page. This occurs when the engine incorrectly handles object types, leading to memory corruption that can be exploited for code execution or data exfiltration.

MitigationUpdate Google Chrome to version 138.0.7204.96 or later to patch the V8 type confusion vulnerability.

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. Locate Chrome executable and version
    Open Chrome, click the three-dot menu > Help > About Google Chrome, or navigate to chrome://settings/help. Note the version number displayed.
    Affected if Version displayed is below 138.0.7204.92 for Stable channel or below 138.0.7204.96 for other release channels
  2. Confirm V8 JavaScript engine is present
    Verify the Chrome installation includes the V8 engine by checking for the v8.dll or libv8.so library file in the Chrome installation directory.
    Affected if V8 engine component is present (this is standard in all Chrome installations, confirming the vulnerable component exists)
  3. Verify no enterprise policy blocks JavaScript
    Check if group policy or enterprise management has disabled JavaScript. In Chrome, navigate to chrome://settings/content/javascript or check local computer policy (gpedit.msc) under Administrative Templates > Google Chrome > Content Settings.
    Affected if JavaScript is enabled (V8 must be active for the vulnerability to be exploitable)

User is affected if their installed Google Chrome version is below 138.0.7204.92 (Stable) or 138.0.7204.96 (other channels) and JavaScript execution is permitted.

Interim mitigation

Update Google Chrome to version 138.0.7204.96 or later to patch the V8 type confusion vulnerability.

Recommended fix High confidence

Chrome 138.0.7204.96 or later

  1. Check the current Chrome version by navigating to chrome://settings/help or selecting Chrome menu > Settings > About Chrome
  2. Download Google Chrome version 138.0.7204.96 or later from the official Chrome download page (chrome.google.com)
  3. Install the updated version of Chrome
  4. Restart Chrome to complete the installation
  5. Verify the version by checking chrome://settings/help - it should show version 138.0.7204.96 or later
Caveat Chrome stable channel upgrades typically have minimal breaking changes; however, some enterprise policies or extensions may require verification for compatibility
