How the CVE Works
CVE-2025-21533 is a privilege escalation vulnerability in Oracle VM VirtualBox’s Core component. It affects versions prior to 7.0.24 and 7.1.6. A low-privileged attacker with local access can exploit improper access controls in the virtualization layer, allowing unauthorized read access to sensitive data within VirtualBox. The flaw stems from insufficient permission validation when handling virtual machine configurations, enabling attackers to bypass security restrictions and access critical system data. The CVSS 3.1 score of 5.5 reflects its moderate impact on confidentiality.
