CVE-2024-21121

Low-privilege host-data disclosure through undisclosed Core flaw

Published Apr 16, 2024 · Updated Mar 27, 2025

Information disclosure in Oracle VM VirtualBox Core before 7.0.16 allows local users to read all data accessible to VirtualBox. Oracle has not published the concrete code locus or faulty operation and identifies only the Core component. Exploitation requires a low-privileged logon where VirtualBox executes and can expose critical data beyond the component's security scope.
