CVE-2025-53026

Host-memory disclosure via uninitialized LSILogic memory

Published Jul 15, 2025 · Updated Jul 15, 2025

Information disclosure in VirtualBox 7.1.10 allows local users with high guest privileges to read critical host-accessible data. The LSILogic module accesses memory without properly initializing it, returning residual host data to the guest. Exploitation requires high-privileged code execution inside a guest; the disclosure can expose host memory and aid a hypervisor compromise.
