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

  - can: dev: can_restart: fix use after free bug After calling netif_rx_ni(skb), dereferencing skb is unsafe.
    Especially, the can_frame cf which aliases skb memory is accessed after the netif_rx_ni() in:
    stats->rx_bytes += cf->len; Reordering the lines solves the issue. (CVE-2021-47668)

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