The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006567 advisory.

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

    scsi: hisi_sas: Grab sas_dev lock when traversing the members of sas_dev.list

    When freeing slots in function slot_complete_v3_hw(), it is possible that     sas_dev.list is being traversed elsewhere, and it may trigger a NULL     pointer exception, such as follows:

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.

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013762 advisory.

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

    scsi: hisi_sas: Grab sas_dev lock when traversing the members of sas_dev.list

    When freeing slots in function slot_complete_v3_hw(), it is possible that     sas_dev.list is being traversed elsewhere, and it may trigger a NULL     pointer exception, such as follows:

    ==>cq thread                    ==>scsi_eh_6

                                    ==>scsi_error_handler()                                       ==>sas_eh_handle_sas_errors()                                         ==>sas_scsi_find_task()                                           ==>lldd_abort_task()     ==>slot_complete_v3_hw()              ==>hisi_sas_abort_task()       ==>hisi_sas_slot_task_free()          ==>dereg_device_v3_hw()         ==>list_del_init()                    ==>list_for_each_entry_safe()
