Vulnerability from github
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.

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