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
Microsoft Edge allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Microsoft Edge Memory Corruption Vulnerability," a different vulnerability than CVE-2016-0155 and CVE-2016-0156.

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 · moderate confidence

Memory corruption vulnerability in Microsoft Edge's scripting engine allows remote attackers to execute arbitrary code or cause a denial of service by tricking users into visiting a crafted malicious website.

MitigationApply Microsoft security updates for Edge (MS16-023 or subsequent patches). Until patched, avoid untrusted websites and consider using an alternative browser.

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. Confirm Microsoft Edge is in use
    Open Microsoft Edge and verify it is your default or active browser. Check Task Manager or browser settings to confirm Edge is running.
    Affected if Microsoft Edge is actively being used as the browser
  2. Identify installed Edge version
    Navigate to edge://settings/help in the Edge address bar, or go to Settings > About Microsoft Edge to view the version number.
    Affected if Version is earlier than the MS16-023 patch level (Edge 12.xx series from early 2016)
  3. Verify scripting engine is active
    The vulnerability triggers when Edge processes JavaScript. Visit any webpage to confirm the scripting engine is operational.
    Affected if Edge is functioning and processing web content with JavaScript enabled

A user is affected if they are running any unpatched version of Microsoft Edge and using it to browse the web, as the vulnerability exploits the scripting engine through malicious websites.
