This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.
The so-called logical triangle is the product of concretizing the pyramid structure. The bottom of the length of the triangle represents the comprehensiveness of the factual basis, and the height represents the strength of the Sowhat (or Why) connection. In other words, the key is to use enough and balanced fact mats to construct the logic that tightly connects Sowhat and Why.
