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
Insufficient validation of untrusted input in GPU in Google Chrome prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to perform a denial of service 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

Insufficient validation of untrusted input in the GPU component of Google Chrome allows a remote attacker with an already compromised renderer process to cause a denial of service by loading a crafted HTML page. This represents a defense-in-depth bypass or secondary exploitation pathway.

MitigationUpdate Google Chrome to version 148.0.7778.168 or later to obtain the patch for this GPU validation 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. Check installed Chrome version
    Navigate to chrome://version in the Chrome browser or run 'google-chrome --version' from command line
    Affected if The displayed version is less than 148.0.7778.168
  2. Verify GPU component is enabled
    Navigate to chrome://gpu in Chrome and check that GPU-related features show as enabled
    Affected if GPU acceleration is enabled (this is the default and required condition for the vulnerability to be exploitable)

You are affected if running any Google Chrome version prior to 148.0.7778.168 with GPU acceleration enabled (the default state).

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 148.0.7778.168 or later
Fixed in 148.0.7778.168
Interim mitigation

Update Google Chrome to version 148.0.7778.168 or later to obtain the patch for this GPU validation issue.

Recommended fix High confidence

Chrome version 148.0.7778.168 or later

  1. Open Chrome and navigate to Settings > Help > About Google Chrome to check the current version
  2. If the version is earlier than 148.0.7778.168, Chrome will automatically check for and apply updates
  3. Restart Chrome after the update completes to ensure the fix is applied
  4. Verify the version is now 148.0.7778.168 or later
Caveat Chrome updates typically have no breaking changes for end users; extensions and settings are preserved
