CVE-2026-71137

High-privileged local hang or crash

Published Aug 18, 2026 · Updated Aug 19, 2026

Denial of service in Oracle VM VirtualBox Core 7.2.14 allows local users to hang or repeatedly crash the hypervisor via unspecified vectors. Oracle has disclosed only that the flaw is in the Core component and has not published the failing function, code path, or operation on attacker-controlled input. Reachability requires high-privileged logon access on a host running VirtualBox, and the published impact is limited to availability loss in VirtualBox, though Oracle marks the scope as changed for possible effects on dependent products.
