Senserva AI Opinion for CVE-2024-38235

Another Hyper-V denial of service bug, this one scoped to Windows 10 1809 x64 and Server 2019 rather than the newer Windows 11 builds seen elsewhere in this batch, carries a Critical 9.8 rating and a 71 percent EPSS score. As with any Hyper-V flaw, the concern is that crashing the hypervisor takes every hosted virtual machine down with it, not just a single workload. It is not confirmed exploited or linked to ransomware.

Do this: Patch Hyper-V hosts on Windows 10 1809 or Server 2019 and confirm guest VM availability after the update.
