Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle VM VirtualBox version 7.2.12. It allows a low-privileged attacker with local access to compromise the software. The attack requires human interaction beyond the attacker's control. Successful exploitation could lead to unauthorized data modification or deletion and partial denial of service.

Detection Guidance

Detection of CVE-2026-47053 requires checking the installed version of Oracle VM VirtualBox. If your system runs version 7.2.12, it is vulnerable. Use commands like 'VBoxManage --version' or check installed packages via system package managers (e.g., 'dpkg -l | grep virtualbox' on Debian/Ubuntu or 'rpm -qa | grep VirtualBox' on RHEL-based systems).

Impact Analysis

If you use Oracle VM VirtualBox 7.2.12, an attacker with local access could alter or delete critical data, or disrupt the software's availability. This could affect virtual machines or stored information under your control.

Compliance Impact

This vulnerability could lead to unauthorized data modification or deletion, which may violate integrity requirements in GDPR or HIPAA. Partial denial of service could also impact availability obligations under these regulations.

Mitigation Strategies

Update Oracle VM VirtualBox to the latest version that addresses this vulnerability. If updating is not immediately possible, restrict user access to the system running VirtualBox and monitor for unusual activity.
