CVE-2026-6726
An information leakage vulnerability in the TCG TPM 2.0 reference code.
Description

An information leakage vulnerability was reported in the TCG TPM 2.0 reference code that could allow a local attacker with elevated privileges to obtain a credential from a TPM-aware CA for a falsified TPM key (such as an Attestation Key, DevID Key or TLS authentication key) and falsify other TPM 2.0 attestations with this key. See also TCG VRT0010.
