CVE-2026-71135

High-privilege denial of service

Published Aug 18, 2026 · Updated Aug 20, 2026

Denial of service in Oracle VM VirtualBox Core in 7.2.14 allows local users to cause a hang or repeatable crash via local access. Oracle has not published the faulty code path or the incorrect operation in the Core component, so the triggering mechanism remains undisclosed in the available primary sources. Exploitation requires high-privilege logon on the host running VirtualBox, and Oracle describes the consequence as a hang or frequently repeatable crash rather than data exposure or unauthorized modification.
