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 kernel in Microsoft Windows 10 Gold allows local users to gain privileges via a crafted application, aka "Windows Kernel Memory Elevation of Privilege 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 · moderate confidence

A memory handling vulnerability in the Windows 10 kernel allows a local authenticated attacker to execute arbitrary code with elevated (kernel-level) privileges by running a specially crafted application, achieving complete system compromise.

MitigationApply the relevant Microsoft security update (MS15-121) to all affected Windows 10 Gold systems, or ensure Windows Update is enabled and systems are patched to at least the November 2015 cumulative update.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Identify the installed Windows 10 build version
    Run `winver` or `systeminfo` from command prompt and note the build number displayed
    Affected if The build number is 10240 (Windows 10 version 1507, also known as Threshold 1)
  2. Verify the exact Windows edition and version string
    Run `winver` and check the "About Windows" dialog or execute `reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v CurrentBuild`
    Affected if The CurrentBuild value is 10240 or the version displays as "Windows 10" without a later feature update designation

The system is affected if it is running Windows 10 1507 (build 10240), as all versions of this specific release are vulnerable to kernel-level privilege escalation via this memory handling flaw.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Interim mitigation

Apply the relevant Microsoft security update (MS15-121) to all affected Windows 10 Gold systems, or ensure Windows Update is enabled and systems are patched to at least the November 2015 cumulative update.

Recommended fix High confidence

Windows 10 1511 (November Update) or later

  1. Open Windows Update by swiping in from the right edge of the screen (or press Windows key + W), then tap or click Settings > Update and recovery > Windows Update.
  2. Tap or click Check for updates, and then wait while Windows looks for the latest updates for your computer.
  3. If updates are found, tap or click Install updates. You may need to restart your computer after the updates are installed.
  4. Alternatively, verify the system has patches installed from November 2015 or later, which addressed this kernel privilege escalation vulnerability.
