CVE-2024-0079

What it actually does

A guest VM user can trigger a NULL-pointer dereference in the host kernel-mode display driver, resulting in a host crash or denial of service.

Why it matters to the business

Virtualized environments relying on NVIDIA GPU drivers may experience sudden host system outages, interrupting workloads and requiring manual recovery.

How an attack unfolds

An attacker with access to a guest VM crafts inputs that reach the kernel-mode driver on the host, dereferencing a NULL pointer and crashing the host hypervisor or driver stack.

How to fix it

Update the NVIDIA GPU Display Driver to the latest vendor-provided version that resolves the NULL-pointer dereference in the kernel mode layer; apply host and guest driver updates consistently across the environment.

How to confirm the fix worked

Verify installed driver versions against vendor release notes, test guest-to-host isolation with synthetic workloads, and confirm absence of NULL dereference crashes under load.

Typical attack path

1. Obtain code execution or user access inside a guest virtual machine
2. Send specially crafted GPU display commands or API calls from the guest
3. Trigger the vulnerable code path in the host kernel-mode driver
4. Cause NULL-pointer dereference leading to host denial of service

How to detect it

Review host kernel and driver logs for NULL dereference crashes or GPU display driver faults originating from guest VM activity; correlate with virtualization platform audit logs for anomalous GPU API usage.

What your security team should do

• Prioritize driver updates on all hosts using affected NVIDIA GPU drivers
• Restrict guest VM access to only trusted users until patches are applied
• Monitor virtualization logs for unexpected host driver crashes
• Review hypervisor configurations to limit guest kernel-mode exposure
