Technical Analysis

CVE-2026-46877 is a vulnerability in the Oracle VM VirtualBox product, specifically in the VMSVGA device component. It affects version 7.2.8 and allows a high privileged attacker with local logon to the infrastructure where Oracle VM VirtualBox runs to compromise the product. The vulnerability has a CVSS 3.1 base score of 6.0 with a vector indicating local attack vector, low attack complexity, high privileges required, no user interaction, scope changed, and high confidentiality impact. Successful exploitation can lead to unauthorized access to critical or all accessible data within Oracle VM VirtualBox. The vulnerability may also impact additional products due to scope change.

Potential Impact

The vulnerability allows unauthorized access to critical data or complete access to all data accessible by Oracle VM VirtualBox. It affects confidentiality but does not impact integrity or availability. The attack requires high privileges and local access, and no user interaction is needed. The scope of impact may extend beyond Oracle VM VirtualBox to other products.

Mitigation Recommendations
