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

  - posix-timers: Prevent RT livelock in itimer_delete() itimer_delete() has a retry loop when the timer is     concurrently expired. On non-RT kernels this just spin-waits until the timer callback has completed,     except for posix CPU timers which have HAVE_POSIX_CPU_TIMERS_TASK_WORK enabled. In that case and on RT     kernels the existing task could live lock when preempting the task which does the timer delivery. Replace     spin_unlock() with an invocation of timer_wait_running() to handle it the same way as the other retry     loops in the posix timer code. (CVE-2023-53815)

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