I'm trying to do boot measurements on RHEL8 machines. And I'm having issues with the following Event in the binary_bios_measurements:

• EventNum: 27
  PCRIndex: 7
  EventType: EV_EFI_VARIABLE_AUTHORITY
  DigestCount: 3
  Digests:
  • AlgorithmId: sha1
    Digest: "3efeb87af48ab5aee7fcbd3514bab719ed865c1c"
  • AlgorithmId: sha256
    Digest: "5f62a2107fa11ce0485fd252d2e6c603cb8ed075861f9513bfed0a26bf6ed62b"
  • AlgorithmId: sha384
    Digest: "841b29f5200c91e1a02e64a6636587bac5b85496a67e6d3c3cf52415a7ab726b4d2259134d84e9082191ac8ee15b7890"
    EventSize: 61
    Event:
    VariableName: 605dab50-e046-4300-abb6-3dd810dd8b23
    UnicodeNameLength: 14
    VariableDataLength: 1
    UnicodeName: MokListTrusted
    VariableData: "01"

Please correct me if I'm wrong but I thinks that as in TCG PC Client PlatformFirmware ProfileSpecification page 54, since the event type is a EV_EFI_VARIABLE_AUTHORITY the UEFI_VARIABLE_DATA.VariableData should be the EFI_SIGNATURE_DATA value
from the EFI_SIGNATURE_LIST that contained the authority that was used to validate the image. And in this boot measurement the VariableData is just "01".

Really appreciate your support on this!
