Guest-to-host code execution via uninitialized pointer
Published Oct 23, 2025 · Updated Feb 26, 2026
Uninitialized pointer access in NVIDIA Virtual GPU Manager 19.1 and earlier allows guest OS users to execute code on the host. A malicious guest triggers the manager to access an uninitialized pointer, but NVIDIA has not disclosed the responsible request path or operation. Access from a configured guest is required; exploitation can disclose or modify host data, elevate privileges, execute code, or interrupt service by an undisclosed failure mode.
