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 without ieee802154_ptr along with devices of the wrong type.","state":0,"publishedAt":"2026-09-25T10:22:14.792+00:00","modifiedAt":"2026-10-19T09:10:04.903+00:00","affected":[{"ecosystem":"Vendor
