CVE-2026-87322 · Severity: high · CVSS 8.4 · Published 2026-10-20

Oracle VM VirtualBox is a virtualization platform that allows organizations to run multiple virtual machines on a single server. A vulnerability in its core component allows a privileged attacker with physical access to the network to take over the virtualization system and potentially compromise all guest virtual machines running on it. This could lead to a complete breach of the entire virtualized infrastructure.

## Technical details

A privilege escalation vulnerability in Oracle VM VirtualBox core allows a high-privileged attacker with access to the physical communication segment (AV:A) to achieve complete system compromise. The vulnerability has a scope change, meaning successful exploitation can significantly impact additional products beyond VirtualBox itself. No authentication or user interaction is required once the attacker has the prerequisite physical network access.

## Affected products
