"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-990429 advisory.

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

    scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put()

    The bnx2fc_destroy() functions are removing the interface before calling
    destroy_work. This results multiple WARNings from sysfs_remove_group() as
    the controller rport device attributes are removed too early.

    Replace the fcoe_port's destroy_work queue. It's not needed.

    The problem is easily reproducible with the following steps.

    Example:

      $ dmesg -w &
      $ systemctl enable --now fcoe
      $ fipvlan -s -c ens2f1
      $ fcoeadm -d ens2f1.802
