Vulnerability from fkie_nvd - Published: 2025-06-10 18:15 - Updated: 2026-08-11 13:17
Severity
Summary
TCG TPM2.0 Reference implementation's CryptHmacSign helper function is vulnerable to Out-of-Bounds read due to the lack of validation the signature scheme with the signature key's algorithm. See Errata Revision 1.83 and advisory TCGVRT0009 for TCG standard TPM2.0
