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

  - sched/core: Do not requeue task on CPU excluded from cpus_mask The following warning was triggered on a     large machine early in boot on a distribution kernel but the same problem should also affect mainline.
    WARNING: CPU: 439 PID: 10 at ../kernel/workqueue.c:2231 process_one_work+0x4d/0x440 Call Trace: <TASK>     rescuer_thread+0x1f6/0x360 kthread+0x156/0x180 ret_from_fork+0x22/0x30 </TASK> Commit c6e7bd7afaeb     (sched/core: Optimize ttwu() spinning on p->on_cpu) optimises ttwu by queueing a task that is     descheduling on the wakelist, but does not check if the task descheduling is still allowed to run on that     CPU. In this warning, the problematic task is a workqueue rescue thread which checks if the rescue is for     a per-cpu workqueue and running on the wrong CPU. While this is early in boot and it should be possible to     create workers, the rescue thread may still used if the MAYDAY_INITIAL_TIMEOUT is reached or     MAYDAY_INTERVAL and on a sufficiently large machine, the rescue thread is being used frequently. Tracing     confirmed that the task should have migrated properly using the stopper thread to handle the migration.
    However, a parallel wakeup from udev running on another CPU that does not share CPU cache observes     p->on_cpu and uses task_cpu(p), queues the task on the old CPU and triggers the warning. Check that the     wakee task that is descheduling is still allowed to run on its current CPU and if not, wait for the     descheduling to complete and select an allowed CPU. (CVE-2022-50100)

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