CVE-2023-0194

What it actually does

An invalid display configuration passed to the kernel-mode NVIDIA GPU display driver can trigger a denial of service condition, typically manifesting as a system crash or driver failure.

Why it matters to the business

Systems equipped with affected NVIDIA GPUs may experience unexpected downtime or loss of graphics functionality, disrupting user productivity and requiring physical intervention or reboot to recover.

How an attack unfolds

An attacker with physical access to a target system supplies an invalid display configuration through connected hardware or local interfaces, causing the kernel-mode driver to mishandle the input and enter a failure state that halts normal operation.

How to fix it

Apply the latest NVIDIA GPU Display Driver updates for Windows and Linux as they become available from the vendor; monitor NVIDIA security bulletins for patches addressing this kernel-mode vulnerability.

How to confirm the fix worked

Verify that the installed NVIDIA display driver version is newer than the vulnerable releases listed in NVIDIA security advisories; test display reconfiguration scenarios in a lab environment to confirm the driver no longer crashes.

Typical attack path

1. Obtain physical access to a system with an affected NVIDIA GPU driver
2. Connect or configure a display device that presents an invalid configuration
3. Trigger the kernel-mode driver to process the malformed configuration
4. Observe system crash or graphics subsystem denial of service

How to detect it

Review system and kernel logs for NVIDIA driver crash signatures or unexpected display subsystem failures occurring after display configuration changes; correlate with physical access events where possible.

What your security team should do

• Prioritize driver updates on all systems with NVIDIA GPUs once patches are released
• Restrict physical access to high-value systems using the affected drivers
• Include NVIDIA driver version checks in regular asset inventory and vulnerability scans
