The remote host is running a version of macOS / Mac OS X that is prior to Catalina Security Update 2021-006.
It is, therefore, affected by a vulnerability :

  • A type confusion issue due to improper state handling allows a malicious application to execute arbitrary code with kernel privileges. (CVE-2021-30869)

Note that Nessus has not tested for this issue but has instead relied only on the operating system’s self-reported version number.
