In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Add TMF to tmr_list handling
An abort that is responded to by iSCSI itself is added to tmr_list but does not go to target core. A LUN_RESET that goes through tmr_list takes a refcounter on the abort and waits for completion. However, the abort will be never complete because it was not started in target core.
Unable to locate ITT: 0x05000000 on CID: 0 Unable to locate RefTaskTag: 0x05000000 on CID: 0. wait_for_tasks: Stopping tmf LUN_RESET with tag 0x0 ref_task_tag 0x0 i_state 34 t_state ISTATE_PROCESSING refcnt 2 transport_state active,stop,fabric_stop wait for tasks: tmf LUN_RESET with tag 0x0 ref_task_tag 0x0 i_state 34 t_state ISTATE_PROCESSING refcnt 2 transport_state active,stop,fabric_stop ...

To fix this, only add abort to tmr_list if it will be handled by target core.
