Technical details

A difficult-to-exploit denial-of-service vulnerability exists in Oracle VM VirtualBox 7.2.16's Core component, reachable via the RDP (Remote Desktop Protocol) network interface. A low-privileged attacker with network access can trigger the vulnerability without user interaction to cause the hypervisor to hang or crash repeatedly, resulting in complete unavailability of the system.
