Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

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 d598266d-7772-4a31-9594-83b76b1fb837 advisory.

    Intel reports:

              A potential security vulnerability in some Intel Processors may allow               denial of service.  Intel released microcode updates to mitigate this               potential vulnerability.


              A potential security vulnerability in some Intel Software Guard               Extensions (Intel SGX) Platforms may allow denial of service.  Intel               is released microcode updates to mitigate this potential               vulnerability.


              Potential security vulnerabilities in the UEFI firmware for some Intel               Processors may allow escalation of privilege, denial of service, or               information disclosure. Intel released UEFI firmware and CPU microcode               updates to mitigate these potential vulnerabilities.


              A potential security vulnerability in some 13th and 14th Generation               Intel Core Processors may allow denial of service.  Intel released               microcode and UEFI reference code updates to mitigate this potential               vulnerability.


              A potential security vulnerability in the Intel Data Streaming               Accelerator (Intel DSA) for some Intel Xeon Processors may allow               denial of service.  Intel released software updates to mitigate this               potential vulnerability.
