The Cryptography Next Generation (CNG) kernel-mode driver (cng.sys) in Windows 10 Gold, 1511, 1607, 1703, and 1709. Windows Server 2016 and Windows Server, version 1709 allows a security feature bypass vulnerability due to the way the kernel-mode driver validates and enforces impersonation levels, aka "Windows Security Feature Bypass Vulnerability". This CVE is unique from CVE-2018-0884.

Security readout for executives and security teams

CVE-2018-0902 is a Windows security feature bypass in Microsoft’s Cryptography Next Generation kernel driver. It concerns how impersonation levels are validated and enforced. The provided sources do not include CVSS, exploit details, or a named workaround, so urgency depends mainly on whether affected legacy Windows versions remain in use. Exposure is most likely in environments still running the listed Windows 10 or Windows Server versions. Supported, fully updated systems may be less exposed, but the bundle does not provide update or KB details to confirm remediation state. Prioritize as a legacy Windows exposure review rather than an emergency, unless affected systems are still operational in sensitive roles. The missing severity score and lack of KEV evidence reduce certainty, but unsupported Windows versions can create broader business risk. Mitigation focus: Inventory endpoints and servers running the affected Windows versions.; Review Microsoft MSRC guidance for applicable security updates or workarounds.; Prioritize remediation for internet-facing, shared, or high-privilege Windows systems..
