CVE-2024-0074

What it actually does

Local attacker with low privileges can access memory beyond the end of an allocated buffer in the NVIDIA GPU Display Driver for Linux, resulting in denial of service via crashes and data tampering through memory corruption.

Why it matters to the business

Systems using NVIDIA GPUs on Linux may experience unexpected crashes or corrupted data, leading to downtime, loss of computational work, and potential integrity issues in graphics or compute workloads.

How an attack unfolds

An attacker with local access to a Linux system running the vulnerable NVIDIA driver crafts input that triggers an out-of-bounds memory access in the display driver, allowing denial of service or modification of adjacent memory regions to tamper with data.

How to fix it

Update the NVIDIA GPU Display Driver for Linux to the latest patched version from the vendor as soon as available; apply driver updates through standard package management or NVIDIA's official channels and reboot affected systems.

How to confirm the fix worked

Verify driver version against vendor release notes after update; test graphics and compute workloads for stability; monitor system logs for related buffer or driver errors during validation.

Typical attack path

1. Obtain local user access on a Linux host with the affected NVIDIA GPU driver
2. Trigger the vulnerable code path via crafted graphics or display operations
3. Cause out-of-bounds memory access to induce crash or corrupt memory
4. Escalate to denial of service or data tampering effects

How to detect it

Review system and kernel logs for NVIDIA driver crashes, out-of-bounds access errors, or unexpected display/compute failures following local user activity; correlate with process execution involving graphics APIs.

What your security team should do

• Prioritize patching NVIDIA Linux GPU drivers across all affected systems
• Restrict local access to systems with GPU workloads where feasible
• Monitor for driver-related stability issues in production environments
