No local access is needed.\nAC:L - The attacker can repeat the attempt over arbitrarily many MPTCP connections and directly influences the option layout (TCP timestamp and MPTCP checksum negotiation, window/data flow, sending ADD_ADDR), so the probabilistic HMAC-bit condition is defeated by simple repetition rather than being beyond attacker control.\nPR:N - Triggering only requires completing the MPTCP handshake and exchanging data with the target \u2014 no credentials or application-level authentication are involved, since the ADD_ADDR/DSS exchange happens in the kernel transport layer.\nUI:N - The ADD_ADDR signal/echo is emitted automatically by the kernel path manager on outgoing packets; no local user action is required.\nS:U - The out-of-bounds write and the memory disclosure are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reserved-but-unwritten TCP option bytes (up to ~20 bytes of uninitialized skb headroom) are transmitted to the remote peer, directly leaking kernel heap contents, and the corrupted `skb_shared_info-\u003enr_frags` causes garbage frag entries to be walked, which can expose further memory.\nI:H - This is an out-of-bounds heap write past the end of the TCP header into `skb_shared_info` (`flags`, `meta_len`, `nr_frags`, `tx_flags`), corrupting adjacent kernel structures \u2014 a memory-corruption primitive usable for page refcount manipulation and further escalation.\nA:H - The confirmed syzbot outcome is a general protection fault in `put_page()` from `skb_release_data()` during `tcp_clean_rtx_queue()` \u2014 a kernel crash reachable from ordinary MPTCP traffic."
