Executive Summary

This vulnerability is in NVIDIA GPU Display Driver for Linux, specifically in the Virtual GPU Manager (vGPU plugin). A guest VM user can send a specially crafted RPC call to the host, causing an out-of-bounds write. This may lead to privilege escalation, data tampering, or denial of service.

Detection Guidance

Detection requires monitoring for unusual RPC calls to the NVIDIA vGPU plugin. Check logs for out-of-bounds write attempts or privilege escalation patterns in guest VMs. Use network monitoring tools to inspect traffic between VMs and the host for malformed RPC requests.

Impact Analysis

If exploited, this vulnerability could allow an attacker with access to a guest VM to gain higher privileges on the host system, alter or corrupt data, or disrupt services causing downtime.

Mitigation Strategies

Apply the latest NVIDIA GPU Display Driver update immediately. Restrict guest VM access to the vGPU plugin via hypervisor settings. Disable RPC interfaces if not required. Monitor for suspicious activity and isolate affected systems.
