Details

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 tmrlist but does not go to target core. A LUNRESET 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.
