16th percentile - higher than 16% of all known CVEs

Summary

In the TCG TPM2.0 Reference implementation, the CryptHmacSign helper function is vulnerable to Out-of-Bounds read due to lack of validation of the signature scheme with the signature key's algorithm. See Errata Revision 1.83 and advisory TCGVRT0009.

Risk Assessment

The vulnerability may lead to data disclosure or malfunction of cryptographic functions, potentially affecting the integrity of signing operations in systems using TPM.

Recommendation

Apply fixes as per TCG recommendations (Errata Revision 1.83) and update the TPM2.0 implementation to a patched version.
