Service interruption via Hyper-V integer underflow
Published May 14, 2024 · Updated Aug 27, 2025
Integer underflow in Hyper-V on affected Windows Server releases allows remote authenticated users to interrupt host service. Microsoft identifies an integer underflow in Hyper-V but has not published the affected routine, input, or arithmetic operation. Low-privileged network access is required; successful exploitation affects availability only, but Microsoft does not specify whether the host hangs, crashes, or reboots.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
