This issue was patched in RHSA-2024:9424.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tpm2-tools package and not the tpm2-tools package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

tpm2 is the source repository for the Trusted Platform Module (TPM2.0) tools. This vulnerability allows attackers to manipulate tpm2_checkquote outputs by altering the TPML_PCR_SELECTION in the PCR input file. As a result, digest values are incorrectly mapped to PCR slots and banks, providing a misleading picture of the TPM state. This issue has been patched in version 5.7.
