If the root CA's private key were compromised, it would cause the entire chain of trust to be compromised, and all subordinate CAs and end users associated with the root CA would be affected. This is because the compromised private key could be used to issue fraudulent certificates, which could be used in man-in-the-middle attacks, phishing attacks, and other types of attacks. As a result, it would be necessary to revoke all certificates issued by the root CA and its subordinate CAs, and issue new certificates with new private keys. This would be a major disruption, and would require a significant amount of effort to mitigate the damage caused by the compromise.
