Title:
  Cannot load certificate stored in NVM

Status in tpm2-openssl package in Ubuntu:
  Fix Released
Status in tpm2-openssl source package in Jammy:
  Confirmed
Status in tpm2-openssl source package in Kinetic:
  Confirmed
Status in tpm2-openssl source package in Lunar:
  Fix Released

Bug description:
  [ Impact ]
  Makes it impossible to use certain TPM functionality via openssl, more precisely extracting the TPM vendor certificate

  [ Test Plan ]
  Run the appropriate command on a machine with an affected TPM.

  Before the fix:

  root at jammy:/tmp# openssl x509 -provider tpm2 -provider default -in handle:0x1c0000a
  WARNING:esys:src/tss2-esys/api/Esys_NV_Read.c:315:Esys_NV_Read_Finish() Received TPM Error 
  ERROR:esys:src/tss2-esys/api/Esys_NV_Read.c:105:Esys_NV_Read() Esys Finish ErrorCode (0x000001c4) 
  Could not read certificate from handle:0x1c0000a
  40C70C33C37F0000:error:4000000C:tpm2::cannot load key::-1:452 tpm:parameter(1):value is out of range or is not correct for the context
  Unable to load certificate

  After the fix:

  root at jammy:~# openssl x509 -provider tpm2 -provider default -in handle:0x1c0000a
  -----BEGIN CERTIFICATE-----
  MIIDBDCCAqmgAwIBAgIUBojh2fQZ3 <...>

  [ Where problems could occur ]
  Theoretically loading from NVM could be affected, but the fix is from upstream and no regressions due to this change have been reported in half a year.
