CVE-2026-101599: Oracle VM VirtualBox privilege escalation in Core component

CVE-2026-101599 · Severity: high · CVSS 7.5 · Published 2026-10-20

Oracle VM VirtualBox is a virtualization platform that allows organizations to run multiple operating systems on a single host computer. A privilege escalation vulnerability in its Core component could allow a low-privileged local attacker to take complete control of the virtualization host and any virtual machines running on it, particularly if the attacker can trick a user into performing an action. This could enable an attacker to access sensitive data across multiple systems or disrupt critical operations.

Technologies: Oracle Vm Virtualbox. Vendors: Oracle.

Technical details

A difficult-to-exploit privilege escalation vulnerability exists in Oracle VM VirtualBox 7.2.20 (and other version 7.x releases) in the Core component. The attack requires local logon access, low privileges, and requires user interaction from a different user. The vulnerability has scope change, meaning successful exploitation impacts systems beyond VirtualBox itself, allowing complete takeover of the hypervisor and potentially all guest virtual machines.
