  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: qualcomm: rmnet: restore skb-\u003Edev on deaggregated frames  rmnet_map_deaggregate() allocates each sub-frame with alloc_skb() and leaves skb-\u003Edev NULL. __rmnet_map_ingress_handler() assigns skb-\u003Edev = ep-\u003Eegress_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-\u003Edev) on a NULL device. An unprivileged user reaches this by unsharing a user\u002Bnet 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.
