CVE-2018-0902

Estado: ModificadaAlta (7.8)—

El controlador (cng.sys) en modo kernel Cryptography Next Generation (CNG) en Windows 10 Gold, 1511, 1607, 1703 y 1709, Windows Server 2016 y Windows Server en su versión 1709 permite una vulnerabilidad de omisión de la característica de seguridad debido a la forma en la que el controlador en modo kernel valida y aplica los niveles de suplantación. Esto también se conoce como "Windows Security Feature Bypass Vulnerability". El ID de este CVE es diferente de CVE-2018-0884.
