The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: iscsi: Fix iscsi_task use after     free Commit d39df158518c (scsi: iscsi: Have abort handler get ref to conn) 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. This results in a iscsi_task use after free, because the common cleanup code will do a put on the     iscsi_task. This reverts the goto and moves the iscsi_get_conn() to after we've checked if the iscsi_task     is valid. (CVE-2021-47427)

Note that Nessus relies on the presence of the package as reported by the vendor.
