The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's     proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use     inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID,     thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by     exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng     up to version 3.3.15, newer versions might be affected also. (CVE-2018-1121)

Note that Nessus relies on the presence of the package as reported by the vendor.
