CVE-2025-53025

Information disclosure via uninitialized BusLogic memory

Published Jul 15, 2025 · Updated Feb 26, 2026

Information disclosure in Oracle VM VirtualBox 7.1.10 allows local users with high guest privileges to read hypervisor memory via BusLogic. The BusLogic module accesses memory before properly initializing it, exposing stale contents across the guest-hypervisor boundary. The gate is high-privileged code execution in a guest, and the disclosure can expose all hypervisor-accessible data or support a larger escape chain.
