The 'TPM2B public' struct is only initialized if the public key is non-NULL, however, it is unconditionally passed to tpm2_calculate_sealing_policy, resulting in use of uninitialized data. If the uninitialized data is lucky enough to be all zeroes, this results eventually results in an error message from tpm2_calculate_name about an unsupported nameAlg field value.
