CVE-2026-35230

Administrator-level hypervisor takeover through undisclosed access control

Published Apr 21, 2026 · Updated Apr 21, 2026

Improper access control in Oracle VirtualBox Core 7.2.6 allows local users with high privileges to take over the hypervisor. Oracle has not published the affected function, access-control decision, or operation that mishandles attacker-controlled input. Exploitation requires high-privileged host access and a high-complexity condition; successful compromise crosses the VirtualBox security scope and affects confidentiality, integrity, and availability.
