TPM Reference Implementation

Summary

The Trusted Computing Group (TCG) Vulnerability Response Team (VRT) has reported a potential out of bounds (OOB) read vulnerability in the Trusted Platform Module (TPM) 2.0 reference implementation code. This vulnerability can be triggered from user-mode applications by sending malicious commands to a TPM 2.0 whose firmware is based on an affected TCG reference implementation.  If successfully exploited, the vulnerability could allow an attacker to read data stored in the TPM or potentially impact TPM availability.

AMD has analyzed the TCG’s report and believes the AMD Firmware TPM (fTPM) is impacted by this vulnerability.
