  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:

Bug description:
  [ Impact ]
  Mandatory digest is not provided by the library

  [ Test Plan ]
  The upstream fix includes a test script:

  https://github.com/tpm2-software/tpm2-openssl/blob/5f55ad3f7fee12201187a29b648e4bc571bcf9fa/test/ec_createak_x509_cms.sh

  [ Where problems could occur ]
  The fix adds a small change in the core of the library, so basic functionality like signing might be affected. However, the fix has been upstream and released for half a year and no regressions have been reported.

  [ Original Description ]
  $ lsb_release -rd
  Description: Ubuntu 22.04 LTS
  Release: 22.04

  $ apt-cache policy tpm2-openssl
  tpm2-openssl:
    Installed: 1.0.1-1
    Candidate: 1.0.1-1
    Version table:
   *** 1.0.1-1 500
          500 http://archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
          100 /var/lib/dpkg/status

  Please see:  https://github.com/tpm2-software/tpm2-openssl/issues/34

  Essentially, any mandatory digest in a public key is ignored by
  tpm2-openssl.
