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
Improper deserialization in WebGL in Google Chrome on Mac prior to 68.0.3440.75 allowed a remote attacker to potentially exploit heap corruption 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 deserialization vulnerability in WebGL component of Google Chrome on MacOS allows remote attackers to corrupt heap memory via specially crafted HTML pages, potentially leading to arbitrary code execution.

MitigationUpdate Google Chrome to version 68.0.3440.75 or later on all Mac systems. In enterprise environments, deploy the update via patch management and verify completion.

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 Google Chrome version
    Open Chrome, click the three-dot menu > Help > About Google Chrome, or navigate to chrome://settings/help. Alternatively, run 'google-chrome --version' or 'C:\Program Files\Google\Chrome\Application\chrome.exe --version' in command prompt on Windows.
    Affected if Version is lower than 68.0.3440.75 (for any operating system where Chrome is installed) or equal to 9.0 on Debian Linux.
  2. Verify WebGL is enabled in Chrome
    Navigate to chrome://settings in the address bar, search for 'WebGL' under Advanced settings, or visit chrome://gpu to check WebGL status under the 'Graphics' section.
    Affected if WebGL is listed as 'Enabled' or 'Hardware accelerated' - the vulnerability exists in the WebGL component, so it only affects environments where WebGL is active.
  3. Confirm operating system is MacOS
    Click the Apple menu > About This Mac on MacOS, or run 'uname -a' in Terminal. The CVE description specifically targets Google Chrome on MacOS.
    Affected if Running MacOS with an affected Chrome version below 68.0.3440.75.
  4. Check Chromium-based browsers on Linux systems
    On Debian 9.0, run 'dpkg -l | grep chromium' or 'apt list --installed | grep -i chrom'. On RHEL 6.0 systems, check for google-chrome or chromium packages using 'rpm -qa | grep -i chrom'.
    Affected if Chromium or Google Chrome version is below 68.0.3440.75 on Debian 9.0 or RHEL 6.0.

You are affected if Google Chrome (or Chromium) version is below 68.0.3440.75 AND WebGL is enabled in the browser on MacOS, Debian 9.0, or RHEL 6.0.
