CVE-2026-47493 · Severity: high · CVSS 7.8 · Published 2026-09-30

NVIDIA vGPU software for Windows and Linux contains a flaw in the GPU kernel driver that allows guest virtual machines to access GPU resources they should not be authorized to use. An attacker exploiting this vulnerability could run malicious code with elevated privileges, steal sensitive data, crash the system, or modify data on the host system.

## Technical details

A privilege escalation vulnerability exists in the GPU kernel driver component of NVIDIA vGPU software, where insufficient access controls allow a guest virtual machine to access privileged GPU resources. The attack requires local access to the virtualized GPU and allows an attacker to escalate privileges, achieve code execution on the host, or cause denial of service. A fix is expected from NVIDIA.
