CVE-2026-71127

High-privilege denial of service

Published Aug 18, 2026 · Updated Aug 25, 2026

Denial of service in Oracle VM VirtualBox Core 7.2.14 allows local users with high privileges to hang or repeatedly crash the hypervisor. Oracle identifies an incorrect type conversion or cast in Core but has not published the affected routine, input, or failing operation. Exploitation requires high-privileged host access and can interrupt VirtualBox and dependent workloads, with impact extending beyond the hypervisor.
