CVE-2024-0075

What it actually does

NULL-pointer dereference in the NVIDIA GPU Display Driver triggered when user-supplied parameters are used without prior validation, resulting in denial of service and limited information disclosure.

Why it matters to the business

Graphics subsystems may crash, producing application or system downtime on Windows and Linux machines that rely on the affected NVIDIA drivers; low likelihood of widespread remote exploitation limits operational risk.

How an attack unfolds

An attacker with local access crafts a call to the driver that supplies invalid parameters; the driver dereferences a NULL pointer without checking, causing a crash and possible minor memory leak.

How to fix it

Install the latest NVIDIA GPU Display Driver updates for Windows and Linux that address the unchecked parameter handling; reboot after installation and verify driver version.

How to confirm the fix worked

Compare installed NVIDIA driver versions against the vendor's security bulletin; attempt reproduction of the NULL dereference in a controlled test environment to confirm the issue is resolved.

Typical attack path

1. Obtain local user or low-privileged access on a system with the vulnerable NVIDIA driver
2. Invoke graphics or display APIs that pass unchecked parameters to the driver
3. Trigger the NULL dereference to induce a kernel or user-mode crash
4. Observe denial of service and any incidental information disclosure

How to detect it

Review system and driver logs for repeated NULL dereference crashes or graphics subsystem failures around the time of suspected activity; correlate with user sessions that have local access.

What your security team should do

• Prioritize driver updates on all systems that use NVIDIA GPUs
• Restrict local access where possible to reduce attack surface
• Monitor vendor release notes for subsequent driver fixes
