CVE-2026-21957
HighSummary
Vulnerability in Oracle VM VirtualBox (component: Core) affects versions 7.1.14 and 7.2.4. It is difficult to exploit, requires high-privileged local access, but can lead to full takeover of VirtualBox. Attacks may impact additional products (scope change).
Risk Assessment
The risk to the organization is high because a successful attack can lead to full takeover of VirtualBox and, due to scope change, compromise confidentiality, integrity, and availability of other systems. However, it requires privileged local access, limiting remote exploitation.
Recommendation
Apply Oracle patches for versions 7.1.14 and 7.2.4 immediately. Restrict local access to VirtualBox infrastructure to trusted administrators and monitor for suspicious activity.
