CVE-2025-23283 is a stack-based buffer overflow in the Virtual GPU Manager component of NVIDIA vGPU software for Linux-style hypervisors. The issue is caused by improper bounds checking of guest-supplied input processed by the Virtual GPU Manager. A malicious guest VM can send crafted GPU operation requests or malformed command buffers that trigger a stack overflow in the host-side vGPU management component, which runs with elevated privileges on the hypervisor. Because the flaw crosses the guest-to-host isolation boundary, successful exploitation may allow compromise of the host environment.
