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
Out of bounds write in GPU in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape 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.

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. Find installed Chrome version
    Open Chrome and navigate to chrome://version, or run 'google-chrome --version' or 'chrome --version' from command line
    Affected if version number is less than 148.0.7778.216
  2. Confirm Chrome is the browser in use
    Check that the Chrome binary is being used (not Chromium or other derivatives) - look at the binary path or about dialog
    Affected if the browser is Google Chrome but not Chromium-built alternatives
  3. Verify GPU rendering is enabled
    Navigate to chrome://gpu or check Chrome settings to confirm hardware acceleration/GPU rendering is enabled
    Affected if GPU rendering is enabled and the browser is vulnerable (version < 148.0.7778.216)

You are affected if Google Chrome is installed with a version lower than 148.0.7778.216 and GPU rendering is active.
