Information disclosure through shared virtual hard disks
Published Apr 15, 2022 · Updated Dec 9, 2025
Information disclosure in Hyper-V Shared Virtual Hard Disks on affected Windows Server releases allows remote authenticated users to expose data. Microsoft has not published the flawed operation or the data boundary crossed when shared virtual disk content is accessed. The Hyper-V role and shared-disk configuration must be present; low-privileged network access suffices, and Microsoft also reports service interruption.

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.
