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.

Отчет
A missing cleanup in fcoe_init() could leave a dangling reference in the FCoE transport list when initialization fails. This results in a use-after-free condition and potential kernel panic when reloading the module. Exploitation requires local administrative privileges.
