CVE-2018-0885

20
FAUCET Score

CVE-2018-0885 is a denial-of-service vulnerability affecting the Microsoft Hyper-V Network Switch across various 64-bit Windows Server and Windows 10 versions. A highly privileged user on a guest operating system can trigger this vulnerability due to improper input validation, leading to a denial of service for the host. While the attack complexity is high and requires privileged access, the potential impact is a complete disruption of the Hyper-V host. There is no public exploit code available, nor is it listed on the KEV catalog, and community discussion and media coverage are minimal, suggesting low current exploitation risk.
