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

  - net: qualcomm: rmnet: restore skb->dev on deaggregated frames rmnet_map_deaggregate() allocates each sub-     frame with alloc_skb() and leaves skb->dev NULL. __rmnet_map_ingress_handler() assigns skb->dev =     ep->egress_dev only on the data path, but a MAP command frame is dispatched to rmnet_map_command() before     that, so rmnet_map_send_ack() runs netif_tx_lock(skb->dev) on a NULL device. An unprivileged user reaches     this by unsharing a user+net namespace, creating an rmnet link over a tap device with     INGRESS_DEAGGREGATION and INGRESS_MAP_COMMANDS, and writing an aggregated frame carrying a flow-control     command to the tap fd. Restore the assignment dropped by 378e25357ac7, so every skb leaving     rmnet_map_deaggregate() has a valid device.
