This results in a iscsi_task use after free, because the common cleanup code will do a put on the iscsi_task.</p> <p>This reverts the goto and moves the iscsi_get_conn() to after we&#39;ve checked if the iscsi_task is valid.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>scsi: iscsi: Fix iscsi_task use after free</p> <p>Commit d39df158518c (&#34;scsi: iscsi: Have abort handler get ref to conn&#34;) added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but then also changed the handling of the case where we detect an already completed task where we now end up doing a goto to the common put/cleanup code.
