AnalysisAIv1 – Sep 15, 2026

Oracle VM VirtualBox 7.2.16 on Windows hosts contains a flaw in the Core component that lets an attacker who already holds low-privileged interactive logon on the host machine take full control of VirtualBox itself, with high impact to confidentiality, integrity, and availability (CVSS 3.1 base 7.8). The vulnerability is local-only (AV:L) and applies exclusively to Windows hosts — Linux and macOS installations are reported as unaffected. No public exploit code or CISA KEV listing is present in the supplied intelligence, so active exploitation is not confirmed at time of analysis.
