Nuvoton NPCT7xx TPM firmware is vulnerable to physical side-channel attacks enabling extraction of Elliptic Curve Diffie-Hellman (ECDH) keys through electromagnetic or timing analysis when an attacker has direct physical access to the TPM device. The vulnerability affects confidentiality of cryptographic material but does not enable code execution or availability attacks. No active exploitation has been publicly reported, and the attack requires specialized knowledge and physical proximity to the target system.
Nuvoton - CWE-305: Authentication Bypass by Primary Weakness An attacker with write access to the SPI-Flash on an NPCM7xx BMC subsystem that uses the Nuvoton BootBlock reference code can modify the. Rated medium severity (CVSS 6.7), this vulnerability is low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 6.0), this vulnerability is low attack complexity. No vendor patch available.
