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
The JSGenericLowering class in compiler/js-generic-lowering.cc in Google V8, as used in Google Chrome before 50.0.2661.94, mishandles comparison operators, which allows remote attackers to obtain sensitive information via crafted JavaScript code.

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. Check Google Chrome version
    Navigate to chrome://settings/help or run 'google-chrome --version' in terminal to see the installed Chrome version
    Affected if Version is 50.0.2661.87 or earlier (versions before 50.0.2661.94)
  2. Check V8 JavaScript engine version embedded in Chrome
    Open Chrome, navigate to chrome://version, look for the V8 version string in the JavaScript engine field
    Affected if V8 version corresponds to Chrome 50.0.2661.87 or earlier releases
  3. Check for V8 on Linux systems with Chromium/Chrome packages
    Run 'rpm -qa | grep -i v8' or 'dpkg -l | grep -i v8' to list installed V8 packages, then run 'v8-version' or check package details for version number
    Affected if V8 package version is 5.0.71.0 or earlier (the version shipped with Chrome 50.0.2661.87)
  4. Identify if running Red Hat Enterprise Linux 6.x Supplementary
    Run 'cat /etc/redhat-release' to confirm the OS version and 'rpm -qa | grep -i chrome' to check for installed Chrome packages
    Affected if System is RHEL 6.0, 6.7, or 6.z Supplementary with Chrome version <= 50.0.2661.87

User is affected if Google Chrome version is 50.0.2661.87 or earlier, or if the embedded V8 engine version is equivalent to that Chrome release, or if RHEL 6 Supplementary has the vulnerable Chrome/V8 package installed.
