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
HTTP.sys in Microsoft Windows 10 Gold and 1511 allows remote attackers to cause a denial of service (system hang) via crafted HTTP 2.0 requests, aka "HTTP.sys Denial of Service Vulnerability."

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

HTTP.sys in Microsoft Windows 10 Gold and 1511 contains a denial of service vulnerability where specially crafted HTTP 2.0 requests can cause the system to hang. The vulnerability is remotely exploitable via network requests to the HTTP service.

MitigationApply Microsoft security updates for CVE-2016-0150 to affected Windows 10 systems. Until patched, consider restricting exposure of HTTP services to untrusted networks or implementing rate limiting on perimeter devices.

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 Windows 10 version and build number
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to identify the exact Windows 10 build. Affected versions are Windows 10 Gold (build 10240) and Windows 10 version 1511 (build 10586).
    Affected if The system runs Windows 10 with build 10240 or 10586 (version 1511).
  2. Verify HTTP service is running
    Run 'sc query http' or check the HTTP Driver service status via Services.msc. Also run 'netsh http show servicestate' to see if HTTP.sys is active.
    Affected if The HTTP service (HTTP.sys driver) is running and handling HTTP requests.
  3. Confirm HTTP 2.0 protocol is enabled
    Check registry key 'HKLM\SYSTEM\CurrentControlSet\Services\HTTP\Parameters' for EnableHttp2Tls and EnableHttp2Cleartext values, or inspect IIS site bindings for HTTP/2 protocol support.
    Affected if HTTP 2.0 is explicitly enabled on the system or IIS site bindings.
  4. Assess network exposure of HTTP services
    Run 'netsh http show urlacl' and 'netstat -ano | findstr :80 :443' to determine if HTTP services are bound to accessible network interfaces.
    Affected if The HTTP service is bound to routable IP addresses and exposed to untrusted networks.

A system is affected if it runs Windows 10 build 10240 or 10586, has HTTP.sys active with HTTP 2.0 enabled, and the HTTP service is network-accessible to untrusted sources.
