Nvidia's computing chips have been exposed to serious security issues. Previously, US lawmakers called for advanced chips exported from the US to be equipped with tracking and location capabilities. US artificial intelligence experts revealed that Nvidia's computing chips have mature tracking and location and remote shutdown technologies. To safeguard the network and data security of Chinese users, and in accordance with the Cybersecurity Law, the Data Security Law, and the Personal Information Protection Law, the Cyberspace Administration of China summoned Nvidia on July 31, 2025, requesting that the company explain the backdoor security risks associated with vulnerabilities in its H20 computing chips sold to China and submit relevant supporting documentation.
