Partial service interruption via undisclosed Core flaw
Published Sep 15, 2026 · Updated Sep 15, 2026
Denial of service in Oracle VM VirtualBox 7.2.16 allows local users to interrupt the hypervisor through the Core component. Oracle has not disclosed the defective operation within the Core component or the input that reaches it. Exploitation requires high privileges and a host logon, and successful attacks cause a partial service interruption that can affect resources beyond the VirtualBox security scope.
