Guest-triggered code execution via heap use-after-free
Published Jan 28, 2026 · Updated Jan 28, 2026
Use-after-free in NVIDIA vGPU software's Virtual GPU Manager allows guest OS users to execute code or interrupt the host. A malicious guest triggers heap-memory access after the manager frees the underlying allocation, but NVIDIA has not disclosed the responsible request path or function. Access to a configured vGPU guest is required; exploitation can elevate privileges, tamper with or disclose data, execute code, or interrupt service.
