Local privilege escalation through undisclosed Hyper-V flaw
Published Oct 11, 2022 · Updated Jan 2, 2025
Elevation of privilege in Microsoft Windows Hyper-V allows local users with low privileges to gain elevated privileges via unspecified vectors. Microsoft has not published the affected Hyper-V locus or the incorrect operation performed on attacker-controlled input. Exploitation requires local low-privileged access and high-complexity conditions, but no separate user interaction; success crosses a security boundary and compromises host confidentiality, integrity, and availability.
