This matches the kernel CNA's established AV:A treatment of NCI packet-parsing bugs, including the direct follow-ups to this very `nci_valid_size()` helper (CVE-2025-40043, CVE-2026-43291).\nAC:L - Triggering only requires delivering a truncated NCI frame (`skb->len < 3`, or `skb->len < 3 + plen`); there is no race, no timing window, and no memory-layout precondition the attacker cannot influence. The condition is deterministic and reproducible on every frame.\nPR:N - `nci_recv_frame()` queues frames and `nci_rx_work()` parses them with no capability, credential, or authentication check anywhere on the path — NFC peering is entirely unauthenticated. No privileges of any kind are needed.\nUI:N - Parsing happens asynchronously in the `rx_wq` workqueue as soon as a frame arrives; no victim action is required beyond the NFC stack being active in its normal discovery/polling state.\nS:U - The out-of-bounds reads, the resulting state corruption, and the downstream heap overflow all occur within the kernel's own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Handlers read up to ~260 bytes past a small heap object (e.g. `rsp_2 = skb->data + 6 + num_supported_rf_interfaces` with an uncontrolled 0–255 offset), and those bytes are copied into `ndev->targets[]` and `ndev->remote_gb`, which are exported to userspace via NFC netlink `NFC_EVENT_TARGETS_FOUND` and LLCP — a direct kernel-memory disclosure primitive.\nI:H - Out-of-bounds bytes are written into kernel state (`conn_info->max_pkt_payload_len`, `ndev->max_ctrl_pkt_payload_len`, `credits_cnt`), and a garbage `max_pkt_payload_len` makes `len = max_pkt_payload_len - skb->len - 1` in `nci_hci_send_data()` underflow, driving `skb_put_data()` past the skb tail for a heap out-of-bounds write.\nA:H - The unbounded reads (`skb->data[-1]` on a zero-length skb, and a 0–255-byte uncontrolled pointer offset) fault or trip KASAN, and the derived length underflow corrupts the heap, producing an oops or panic that is repeatable on demand." } ] }
