According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 10.6.3. It is, therefore, affected by a vulnerability as referenced in the TNS-2023-40 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

the remote host, which could lead to a denial of service condition. Tenable has released Nessus
10.6.3 to address these issues. The installation files can be obtained from the Tenable Downloads Portal
