Remote code execution via Hyper-V use-after-free
Published Mar 12, 2024 · Updated May 3, 2025
A use-after-free in Microsoft Windows Hyper-V allows remote attackers to execute arbitrary code through an undisclosed network vector. The published record identifies reuse of freed memory in Hyper-V but does not name the affected routine, object, or triggering input. No privileges or user interaction are required, but high attack complexity constrains exploitation.

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.
- Affected versionversion=10.0.10240.0 <10.0.10240.20526
