CVE-2025-53028

Hypervisor code execution via VMSVGA out-of-bounds write

Published Jul 15, 2025 · Updated Feb 26, 2026

Out-of-bounds write in the VMSVGA device in Oracle VM VirtualBox 7.1.10 allows guest OS users to execute code in the hypervisor. The virtual device fails to validate guest-supplied data before writing it, allowing data to pass the end of an allocated buffer. Exploitation requires high-privileged code execution in a guest and can take over the hypervisor, affecting host confidentiality, integrity, and availability.
