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 Virtual DOS Machine (VDM) in the Windows Kernel in Microsoft Windows NT 4.0; 2000 SP4; XP SP2; Server 2003, 2003 SP1, and 2003 SP2; and Windows Vista before June 2006; uses insecure permissions (PAGE_READWRITE) for a physical memory view, which allows local users to gain privileges by modifying the "zero page" during a race condition before the view is unmapped.

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

The Virtual DOS Machine (VDM) in the Windows Kernel uses PAGE_READWRITE permissions for a physical memory view, creating a race condition where local users can modify the 'zero page' before the view is unmapped, leading to privilege escalation.

MitigationApply the Microsoft security update for this vulnerability. As a defense-in-depth measure, limit local access to systems and monitor for suspicious processes attempting to manipulate memory views.

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 version
    Run 'winver' or check system properties to identify the exact Windows version and service pack level
    Affected if The system is Windows 2000 (any version), Windows 2003 Server (gold, SP1, or SP2), or Windows XP (any version)
  2. Verify VDM component presence
    Check for the presence of the Virtual DOS Machine (VDM) subsystem by examining running processes or kernel modules related to VDM or DOS emulation
    Affected if VDM subsystem is present and accessible to local users on the affected Windows versions
  3. Identify processes with memory manipulation access
    Review running processes for applications that attempt to manipulate physical memory views or access the zero page, which could indicate exploitation attempts
    Affected if Suspicious processes are observed manipulating memory views with PAGE_READWRITE permissions
  4. Check for privilege escalation indicators
    Audit system for unexpected privilege escalation by reviewing new administrative accounts, modified service configurations, or unauthorized scheduled tasks
    Affected if Evidence of unauthorized privilege escalation is found on the system

A system is affected if it runs Windows 2000, Windows 2003 Server (gold/SP1/SP2), or Windows XP, and has the VDM subsystem accessible to local users.
