"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-013079 advisory.

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

    scsi: mpt3sas: Fix crash in transport port remove by using ioc_info()

    During mpt3sas_transport_port_remove(), messages were logged with
    dev_printk() against &mpt3sas_port->port->dev. At this point the SAS
    transport device may already be partially unregistered or freed, leading
    to a crash when accessing its struct device.

    Using ioc_info(), which logs via the PCI device (ioc->pdev->dev),
    guaranteed to remain valid until driver removal.
