CVE-2026-46877

Disclosure of all virtualization-accessible data

Published Jun 16, 2026 · Updated Jun 16, 2026

Information disclosure in Oracle VM VirtualBox 7.2.8 allows local users with high privileges to read all VirtualBox-accessible data. The issue resides in the VMSVGA virtual graphics device, but Oracle has not published the flawed operation or the input that triggers it. Exploitation requires a high-privilege logon on the host where VirtualBox runs; the reported consequence is disclosure only, with no integrity or availability impact.
