The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the b6dd9d93-e09b-11ee-92fc-1c697a616631 advisory.

  • Intel reports: 2024.1 IPU - Intel Processor Bus Lock Advisory A potential security vulnerability in the bus lock regulator mechanism for some Intel Processors may allow denial of service. Intel is releasing firmware updates to mitigate this potential vulnerability. 2024.1 IPU - Intel Processor Return Predictions Advisory A potential security vulnerability in some Intel Processors may allow information disclosure. 2024.1 IPU - Intel Atom Processor Advisory A potential security vulnerability in some Intel Atom Processors may allow information disclosure. 2024.1 IPU - Intel Xeon Processor Advisory A potential security vulnerability in some 3rd and 4th Generation Intel Xeon Processors when using Intel Software Guard Extensions (SGX) or Intel Trust Domain Extensions (TDX) may allow escalation of privilege. 2024.1 IPU OOB - Intel Xeon D Processor Advisory A potential security vulnerability in some Intel Xeon D Processors with Intel Software Guard Extensions (SGX) may allow information disclosure. (CVE-2023-22655, CVE-2023-43490)

  • This CVE was assigned by Intel. Please see CVE-2023-28746 on CVE.org for more information.
    (CVE-2023-28746)

  • Non-transparent sharing of return predictor targets between contexts in some Intel Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2023-38575) (CVE-2023-38575, CVE-2023-39368)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
