The version of openssl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-2097 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of openssl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2022-2097 advisory.
- AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt
the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was
preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes
of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and
DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q
(Affected 1.1.1-1.1.1p). (CVE-2022-2097)
