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
Google Chrome before 50.0.2661.75 does not properly consider that frame removal may occur during callback execution, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted extension.

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 if Google Chrome is installed
    On Linux, run: which google-chrome or dpkg -l | grep chrome or rpm -qa | grep chrome. On Windows, check Program Files/Google/Chrome/Application/chrome.exe exists.
    Affected if Google Chrome browser is not installed on the system
  2. Determine installed Chrome version
    Run: google-chrome --version or google-chrome -version. On Windows, right-click chrome.exe > Properties > Details > File Version.
    Affected if Unable to retrieve version number - Chrome may be installed but version detection failed
  3. Compare version against vulnerable range
    Compare your installed version number to the affected range: any version <= 49.0.2623.112 is vulnerable. Version 50.0.2661.75 and later are patched.
    Affected if Installed Chrome version is 49.0.2623.112 or lower, meaning the use-after-free in frame removal callback handling is present

If Google Chrome version 49.0.2623.112 or lower is installed, the environment is affected by this use-after-free vulnerability in frame removal during callback execution.
