Per kernel scoring convention Bluetooth is Adjacent.\nAC:L - The attacker controls its own controller\u0027s LMP timing and simply starts SSP immediately upon connection-complete, which reliably beats the host\u0027s extra Read Remote Extended Features HCI command plus LMP round trip; the attempt can also be repeated without limit.\nPR:N - HCI_EV_IO_CAPA_REQUEST and HCI_EV_SIMPLE_PAIR_COMPLETE are handled during the pre-bonding pairing phase, before any credentials or link key exist, and the guard is hit before even the HCI_MGMT/HCI_BONDABLE policy checks. No privileges on the target are required.\nUI:N - Reaching the code needs only an ACL connection to a connectable or accept-listed host, which is the default steady state for embedded, automotive, audio, kiosk and previously-paired deployments. No victim action is needed to trigger the event sequence.\nS:U - The corrupted state (hci_conn reference count and connection lifetime) lives entirely within the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The unbalanced hci_conn_drop() reintroduces a reference-count underflow (CWE-911) on a kernel object, which can drive the connection to teardown while pairing-state-machine work still references it \u2014 a use-after-free class defect whose reclaimed memory can be leveraged for kernel information disclosure.\nI:H - The same refcount underflow lets an attacker-controlled peer desynchronize hci_conn lifetime accounting, and a freed-then-reused hci_conn under remote-influenced heap grooming yields write/control-flow primitives; the guidance treats use-after-free as High integrity impact.\nA:H - A remote peer can reliably stall SSP so pairing never completes, trigger WARN_ON(refcnt \u003c 0) in hci_conn_timeout() (a panic on panic_on_warn builds such as Android and hardened distro kernels), abort a live ACL link prematurely, or leak connections that never time out and exhaust the controller\u0027s ACL slots."

No privileges on the target are required.\\nUI:N - Reaching the code needs only an ACL connection to a connectable or accept-listed host, which is the default steady state for embedded, automotive, audio, kiosk and previously-paired deployments. No victim action is needed to trigger the event sequence.\\nS:U - The corrupted state (hci_conn reference count and connection lifetime) lives entirely within the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\\nC:H - The unbalanced hci_conn_drop() reintroduces a reference-count underflow (CWE-911) on a kernel object, which can drive the connection to teardown while pairing-state-machine work still references it \\u2014 a use-after-free class defect whose reclaimed memory can be leveraged for kernel information disclosure.\\nI:H - The same refcount underflow lets an attacker-controlled peer desynchronize hci_conn lifetime accounting, and a freed-then-reused hci_conn under remote-influenced heap grooming yields write/control-flow primitives; the guidance treats use-after-free as High integrity impact.\\nA:H - A remote peer can reliably stall SSP so pairing never completes, trigger WARN_ON(refcnt \u003c 0) in hci_conn_timeout() (a panic on panic_on_warn builds such as Android and hardened distro kernels), abort a live ACL link prematurely, or leak connections that never time out and exhaust the controller\u0027s ACL slots.\"}]}],
