    This is caused by mpt3sas_base_sync_reply_irqs() using an invalid reply_q
    pointer outside of the list_for_each_entry() loop. At the end of the full
    list traversal the pointer is invalid.

    Move the _base_process_reply_queue() call inside of the loop.

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.");
