CVE-2026-47499 · Severity: high · CVSS 7.8 · Published 2026-09-30

NVIDIA vGPU Virtual GPU Manager is a virtualization platform that allows servers to share GPUs across multiple guest virtual machines. A flaw in the kernel mode layer permits a guest VM to trigger an out-of-bounds memory read, potentially leading to code execution, privilege escalation, information disclosure, or denial of service on the host system.

## Technical details

An out-of-bounds read vulnerability exists in the kernel mode layer of NVIDIA vGPU Virtual GPU Manager, exploitable by a guest VM through unvalidated kernel mode operations. A guest can trigger this flaw to read memory outside intended bounds, which may be leveraged for information disclosure or as a stepping stone to code execution and privilege escalation on the host. No public information indicates whether fixes are available at this time.
