CVE-2018-8637

Estado: ModificadaMedia (5.5)—

Existe una vulnerabilidad de divulgación de información en el kernel de Windows que podría permitir que un atacante recupere información, lo que podría conducir a una omisión de KASLR (Kernel Address Space Layout Randomization) del kernel. Esto también se conoce como como "Win32 Information Disclosure Vulnerability". Esto afecta a Windows 10 Servers, Windows 10 y Windows Server 2019.
