AnalysisAIv1 – Mar 12, 2026

Windows Kerberos authentication in Server 2012 and Windows 10 (versions 1607, 1809) contains a race condition that enables unauthenticated remote attackers to circumvent security feature protections. The synchronization flaw in concurrent resource access allows attackers to bypass intended security controls without user interaction over the network. No patch is currently available for this vulnerability.
