On August 25, international media outlets reported that investment bank Jefferies released a recent report indicating that NVIDIA's H100 chip has been prohibited from procurement due to security concerns, resulting in Chinese manufacturers ceasing their purchases of the chip. Prior to this, the Cyberspace Administration of China had summoned NVIDIA, highlighting security risks such as vulnerabilities and backdoors associated with the H100 chip. Despite being designed specifically for the Chinese market, the chip was found to possess capabilities for tracking and remote shutdown, potentially leading to the leakage of device information and posing significant security threats. NVIDIA has refuted these allegations, yet the future of the H100 chip remains uncertain and shrouded in controversy.
