CVE-2022-42262

What it actually does

Unvalidated input index in the Virtual GPU Manager leads to buffer overrun, enabling memory corruption that can result in data tampering, information disclosure, or denial of service.

Why it matters to the business

Virtualized GPU environments may suffer service disruptions, unauthorized data exposure, or system instability affecting hosted workloads across multiple hypervisors and NVIDIA GPU products.

How an attack unfolds

An attacker with local access supplies a crafted input index to the vulnerable vGPU plugin, triggering a buffer overrun to corrupt memory and achieve tampering, disclosure, or denial of service.

How to fix it

Apply the latest NVIDIA vGPU software and GPU display driver updates addressing the input validation flaw in the Virtual GPU Manager across all affected products.

How to confirm the fix worked

Confirm NVIDIA vGPU software versions match or exceed patched releases listed in NVIDIA security bulletins and test the vGPU plugin for proper index validation.

Typical attack path

1. Obtain local access on a host running vulnerable NVIDIA vGPU software
2. Interact with the Virtual GPU Manager plugin
3. Submit malicious input index to trigger buffer overrun
4. Exploit resulting memory corruption for tampering, disclosure, or DoS

How to detect it

Inspect vGPU plugin logs and system event records for abnormal index handling errors or unexpected memory access patterns on GPU hosts.

What your security team should do

• Apply available NVIDIA vGPU patches immediately on all affected hypervisors and GPU products
• Limit local privileged access to GPU hosts
• Monitor NVIDIA release notes for fixed versions
