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 data validation in WebGL in Google Chrome prior to 64.0.3282.119 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.

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

A data validation vulnerability in WebGL component of Google Chrome allows a remote attacker to read out-of-bounds memory by tricking users into visiting a crafted HTML page. The insufficient validation of WebGL input parameters enables an information disclosure attack without requiring code execution.

MitigationUpdate Google Chrome to version 64.0.3282.119 or later to patch the WebGL 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. Verify Google Chrome installation
    Check if Google Chrome is installed by looking for the executable at /usr/bin/google-chrome or /Applications/Google Chrome.app on macOS. On Windows, check Program Files for Google Chrome folder.
    Affected if Google Chrome is found on the system and the version is below 64.0.3282.119
  2. Determine installed Chrome version
    Open Chrome and navigate to chrome://settings/help, or run 'google-chrome --version' in the terminal on Linux, or '"C:\Program Files\Google\Chrome\Application\chrome.exe" --version' in Command Prompt on Windows.
    Affected if The displayed version number is less than 64.0.3282.119
  3. Confirm WebGL is enabled
    In Chrome, navigate to chrome://settings and search for 'WebGL', or visit a WebGL test page (such as webgl.org) to verify that WebGL is functional and rendering.
    Affected if WebGL is actively enabled and functional in the browser, creating the attack surface for this vulnerability
  4. Check for Linux package versions (Debian/RHEL)
    On Debian-based systems, run 'dpkg -l | grep google-chrome'. On RHEL-based systems, run 'rpm -qa | grep chrome'. For Debian Linux 8/9 or RHEL 6, also check if the system has legacy Chrome packages installed.
    Affected if The installed package version is below 64.0.3282.119 on Debian 8.0, 9.0, or RHEL 6 Desktop/Server/Workstation

You are affected if Google Chrome (or a compatible Chromium-based browser) is installed with WebGL enabled and the version is earlier than 64.0.3282.119.
