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

  - parisc: led: Fix potential null-ptr-deref in start_task() start_task() calls     create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref     may happen: start_task() create_singlethread_workqueue() # failed, led_wq is NULL queue_delayed_work()     queue_delayed_work_on() __queue_delayed_work() # warning here, but continue __queue_work() # access     wq->flags, null-ptr-deref Check the ret value and return -ENOMEM if it is NULL. (CVE-2022-50415)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004288 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    parisc: led: Fix potential null-ptr-deref in start_task()

    start_task() calls create_singlethread_workqueue() and not checked the     ret value, which may return NULL. And a null-ptr-deref may happen:

    start_task()         create_singlethread_workqueue() # failed, led_wq is NULL         queue_delayed_work()             queue_delayed_work_on()
                __queue_delayed_work()  # warning here, but continue
                    __queue_work()      # access wq->flags, null-ptr-deref

    Check the ret value and return -ENOMEM if it is NULL.

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

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