In Nuvoton NPCT75x TPM 1.2 firmware 7.4.0.0, a local authenticated malicious user with high privileges could potentially gain unauthorized access to TPM non-volatile memory. NOTE: Upgrading to firmware version 7.4.0.1 will mitigate against the vulnerability, but version 7.4.0.1 is not TCG or Common Criteria (CC) certified.
