NVIDIA warns users to enable System Level ECC to protect against Rowhammer attacks on GDDR6 GPU memory, following research demonstrating successful bit-flip attacks. The findings highlight the importance of hardware memory protections for maintaining data integrity in high-performance workloads. #Rowhammer #GDDR6
Keypoints
- NVIDIA advises enabling System Level ECC to defend against Rowhammer attacks on GPUs.
- Research from the University of Toronto demonstrated a successful bit-flip attack on NVIDIA A6000 GPUs.
- Rowhammer involves repeatedly accessing memory rows to induce data corruption via bit-flips.
- Modern GPUs with on-die ECC, like Blackwell RTX 50 Series, have built-in protections.
- Enabling ECC may cause a minor performance slowdown but significantly enhances data security.
