CRITICALtpm2-tools < 5.7 - Digest Mapping Manipulation via TPML_PCR_SELECTION Alteration
Title source: llmDescription
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.
