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
Use after free in ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to execute arbitrary code 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

Use-after-free vulnerability in ANGLE (graphics layer) in Google Chrome versions prior to 148.0.7778.216. An attacker with a compromised renderer process can exploit this via a crafted HTML page to achieve arbitrary code execution.

MitigationUpdate Google Chrome to version 148.0.7778.216 or later. In enterprise environments, ensure automatic updates are enabled or deploy the patched version via standard software distribution mechanisms.

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
    Open Chrome and navigate to chrome://settings/help, or run 'google-chrome --version' (Linux) or check 'C:\Program Files\Google\Chrome\Application\chrome.exe --version' (Windows). Compare the reported version against 148.0.7778.216 (or 148.0.7778.215).
    Affected if The installed version is earlier than 148.0.7778.216 (or 148.0.7778.215, depending on the branch). Versions prior to these are affected.
  2. Verify Chrome renderer process isolation
    The vulnerability requires a compromised renderer process to exploit the ANGLE graphics library. Check if Chrome is running with default sandboxing enabled. This is not a user-configurable check for the vulnerability itself but confirms the attack surface.
    Affected if This check does not determine vulnerability; it only confirms the attack vector exists in default Chrome configurations.
  3. Confirm ANGLE library presence
    ANGLE is built into Chrome as part of the graphics stack and cannot be independently verified. No separate file or module check is needed beyond confirming Chrome itself is installed.
    Affected if This step confirms the vulnerable component exists within Chrome installations.

A user is affected if their installed Google Chrome version is earlier than 148.0.7778.216 (or 148.0.7778.215 on the other branch), as the UAF flaw exists in the ANGLE graphics library of those versions.
