Description
In the Linux kernel, the following vulnerability has been resolved: scsi: fcoe: Fix transport not deattached when fcoe_if_init() fails fcoe_init() calls fcoe_transport_attach(&fcoe_sw_transport), but when fcoe_if_init() fails, &fcoe_sw_transport is not detached and leaves freed &fcoe_sw_transport on fcoe_transports list.
