Local hypervisor takeover through undisclosed Core flaw

Published Sep 15, 2026 · Updated Sep 15, 2026

Unspecified Core vulnerability in Oracle VM VirtualBox 7.2.16 allows local users to take over the hypervisor through local interaction. Oracle has not disclosed the flawed Core operation, the input it mishandles, or the path by which that input crosses the virtualization boundary. Exploitation requires a low-privileged account on the host and interaction by another person, and successful attacks can compromise VirtualBox and significantly affect additional products.
