The random REKEY_TIMEOUT jitter and host worker scheduling are not controlled by the attacker.\nPR:N - A byte-identical captured response passes wg_cookie_validate_packet() and the encrypted_nothing check in message_decrypt() when replayed, so an on-path attacker need not possess a configured peer's private or preshared key.\nUI:N - The attacker delays and duplicates the UDP response, while wg_expired_retransmit_handshake() automatically queues the intermediate initiation; no victim action is required during exploitation.\nS:U - The duplicate sessions remain within the same peer's noise_keypairs and compromise traffic handled by that WireGuard device under the same kernel security authority; no VM, IOMMU, or other authority boundary is crossed.\nC:H - Both calls to wg_noise_handshake_begin_session() run derive_keys() on the same chaining_key, while each keypair_create() starts sending_counter at zero. Reusing ChaCha20 keys and nonces across transport packets can expose substantial tunnel plaintext.\nI:H - encrypt_packet() authenticates transport ciphertext with ChaCha20-Poly1305 using the duplicated key and reset counter as its nonce. Reusing that Poly1305 one-time key permits an on-path attacker to construct forged authenticated tunnel packets for colliding counters.\nA:L - The reset sending_counter repeats counters already used by the first session, so the peer's counter_validate() replay window discards colliding packets until the new counter catches up or a rekey occurs.
