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 ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: Critical)

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

Out-of-bounds write vulnerability in ANGLE (a graphics library used by Chrome for WebGL rendering) allows a remote attacker to achieve arbitrary code execution through a specially crafted HTML page. This memory corruption flaw in the graphics subsystem can be triggered simply by a user visiting a malicious webpage.

MitigationUpdate Google Chrome to version 148.0.7778.216 or later to patch the ANGLE vulnerability. Organizations should deploy the browser update across affected endpoints and verify web applications relying on WebGL continue to function correctly.

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. Verify Google Chrome is installed
    On Windows, check for chrome.exe in Program Files or Program Files (x86). On macOS, check /Applications/Google Chrome.app. On Linux, run which google-chrome or check /usr/bin/google-chrome.
    Affected if Google Chrome is not present on the system - not vulnerable
  2. Determine installed Chrome version
    Open Chrome, click the three-dot menu, select Help > About Google Chrome, or navigate to chrome://settings/help. Note the version number displayed.
    Affected if Version is less than 148.0.7778.215 (or 148.0.7778.216 for certain branches) - potentially vulnerable
  3. Confirm WebGL is enabled
    Navigate to chrome://settings in the address bar, search for 'Hardware acceleration' or 'WebGL', or inspect chrome://gpu to verify WebGL status. WebGL rendering uses the ANGLE library.
    Affected if WebGL is disabled - vulnerability cannot be triggered despite vulnerable version being present
  4. Compare version against affected range
    If version is below 148.0.7778.215, compare your exact version number to the affected range: < 148.0.7778.216 and < 148.0.7778.215.
    Affected if Installed version falls below 148.0.7778.215 AND WebGL is enabled - environment is affected

A user is affected if they have Google Chrome installed with a version below 148.0.7778.215 and WebGL is enabled, as the ANGLE library vulnerability requires WebGL to be active for malicious graphics content to trigger the out-of-bounds write.
