vulnerability has been resolved:\n\nieee802154: 6lowpan: fix NULL dereference in lowpan_newlink\n\nTUNSETLINK allows a TUN device to change its link-layer type to\nARPHRD_IEEE802154 without initializing ieee802154_ptr. lowpan_newlink()\nchecks only the device type before dereferencing the pointer, so an\nRTM_NEWLINK request can trigger a NULL pointer dereference.\n\nReject devices
