reliably hit the missing hold/put window; no conditions beyond the attacker\u0027s control are required.\\nPR:N - LE ACL/L2CAP signaling is processed for an established HCI LE connection with no pairing, encryption, or local capability check before l2cap_le_command_rej runs.\\nUI:N - Exploitation only needs an LE link and a matching pending channel ident; no additional victim action is required at exploit time once the stack is in that normal operational state.\\nS:U - Impact is confined to the local kernel Bluetooth/L2CAP authority (memory corruption / privilege escalation on the host), with no cross-boundary escape.\\nC:H - This is a use-after-free of struct l2cap_chan; UAF enables heap reuse and arbitrary kernel read primitives.\\nI:H - The same UAF enables heap spraying and
