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. This causes panic when reinserting module. BUG: unable to handle page fault for address: fffffbfff82e2213 RIP: 0010:fcoe_transport_attach+0xe1/0x230 [libfcoe] Call Trace: <TASK> do_one_initcall+0xd0/0x4e0 load_module+0x5eee/0x7210 ...

Executive Summary

This vulnerability occurs in the Linux kernel's FCoE (Fibre Channel over Ethernet) subsystem. Specifically, when the function fcoe_if_init() fails during initialization, the transport object (&fcoe_sw_transport) is not properly detached from the fcoe_transports list. This leaves a freed transport object still referenced, which can cause a kernel panic when the module is reinserted.

Impact Analysis

The vulnerability can cause the Linux kernel to panic (crash) when the affected module is reinserted. This can lead to system instability, downtime, and potential loss of availability of services relying on the FCoE subsystem.
