CNVD stands for China National Vulnerability Database for Information Security. Managed by the China National Computer Network Emergency Response Technical Team/Coordination Center (CNCERT/CC), CNVD is a centralized platform for collecting, analyzing, and sharing information about security vulnerabilities in software and hardware products. The database supports national cybersecurity efforts by providing timely vulnerability disclosures, coordinating defense responses, and facilitating the mitigation of risks across government, enterprises, and the public. CNVD plays a crucial role in China’s cybersecurity infrastructure, working closely with domestic and international organizations to enhance information security awareness and incident response capabilities.
