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. This causes panic when
reinserting module.

 BUG: unable to handle page fault for address: fffffbfff82e2213
