Senserva AI Opinion for CVE-2024-38159

This Critical Severity (CVSS 9.8) Remote Code Execution flaw lives in Windows Network Virtualization, the SDN layer used by Hyper-V hosting environments, and affects the aging Windows Server 2016 and Windows 10 1607 platforms. With EPSS at 71%, the exploitation math is bad for any datacenter still running virtualization workloads on Server 2016. Compromise at the network-virtualization layer threatens every VM whose traffic flows through the host.

Do this: Patch Server 2016 Hyper-V hosts using network virtualization now, and use the finding to press the case for migrating them to a supported-longer platform.
