The TPM library specification states that the TPM must comply with NIST SP800-90 A.
https://trustedcomputinggroup.org/membership/certification/tpm-certified-products/
shows that the TPMs get third party certification, Common Criteria EAL 4+.
While it's theoretically possible that an attacker could compromise both the TPM vendors and the evaluation agencies, we do have EAL 4+ assurance against both 1 and 2.
