The length value and the copied payload both originate from a remote peer's packet on the wire.\nAC:H - The addition can only wrap if `gl->tot_len` approaches 2^32, but `RSPD_LEN_M` masks the hardware-reported length to 31 bits and the SGE fragment loop bounds it to real received packet data, so the attacker cannot supply a wrapping value. It additionally requires a 32-bit kernel hosting a Chelsio T4/T5 RDMA adapter — a rare configuration entirely outside the attacker's control.\nPR:N - The path is reached during passive-open connection setup from an inbound SYN, before any iWARP/RDMA connection is established or any credentials are exchanged. An unauthenticated remote host is sufficient.\nUI:N - Packet processing happens in the NAPI/interrupt receive path with no user action required; the administrator merely having an iWARP listener bound is a deployment precondition, not victim interaction.\nS:U - The overflow corrupts kernel slab memory within the same kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - An undersized `alloc_skb()` followed by `__skb_put()` of the full unwrapped length leaves the skb describing memory beyond its allocation, so subsequent processing of that skb reads adjacent slab contents, and the resulting heap corruption is leverageable for arbitrary kernel memory disclosure.\nI:H - `skb_copy_to_linear_data_offset()` writes attacker-supplied packet bytes past the end of the undersized allocation, giving a controlled-content heap buffer overflow suitable for corrupting adjacent objects and hijacking control flow.\nA:H - Overwriting adjacent slab objects with wire data reliably corrupts kernel state and panics the machine, and the allocation of a near-2GB skb would itself destabilize the system under GFP_ATOMIC in the receive path." } ] } ],
