CVE-2026-71139

Admin-triggered hang or repeated 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 product via unspecified vectors. Oracle has not disclosed the failing function or the operation on untrusted input in the Core component, and the public record does not identify a patch diff or root cause. Reachability is local and requires high-privileged logon access to the host running VirtualBox, so the published impact is limited to availability interruption rather than code execution or data exposure.
