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 2000 SP4, XP SP2 and SP3, Server 2003 SP2, and Vista Gold does not properly allocate memory for the destination key associated with a symbolic-link registry key, which allows local users to gain privileges via a crafted application, aka "Windows Kernel Memory Allocation 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

The Windows Kernel fails to properly allocate memory for destination keys associated with symbolic-link registry keys, allowing local attackers to craft malicious applications that exploit this memory allocation flaw to elevate privileges to SYSTEM level.

MitigationApply the relevant Microsoft security patch (MS10-015) for affected Windows versions. For end-of-life systems that cannot be patched, implement compensating controls such as restricting local user permissions, application whitelisting, and preventing execution of untrusted code.

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 Windows version
    Run 'winver' or check System Properties, or use 'wmic os get Caption,Version' from command prompt
    Affected if Version shows Windows 2000, Windows XP, Windows Server 2003, or Windows Vista (any edition)
  2. Confirm patch KB976749 is not installed
    Check for the presence of security update KB976749 by running 'wmic qfe list' or viewing Installed Updates in Control Panel
    Affected if The patch KB976749 is absent from the installed updates list, indicating MS10-015 has not been applied
  3. Verify kernel vulnerability status
    Since this is a kernel-level flaw in symbolic-link registry key handling with no configurable workaround, the vulnerability exists if the OS is an affected version AND KB976749 is not installed
    Affected if System runs an unpatched Windows 2000/XP/2003/Vista installation

A system is affected if it runs Windows 2000, Windows XP, Windows Server 2003, or Windows Vista and lacks the KB976749 security update (MS10-015).
