CVSS 6.5 MEDIUM
`lib/kadm5/kadm_rpc_xdr.c` in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because `_xdr_kadm5_principal_ent_rec` does not validate the relationship between `n_key_data` and the `key_data` array count.
