| enl::TransportManager::updateReceiveBuffer_() nullptr deref
| enl::TransportManager::updateReceiveBuffer_() is called when the ENL framework receives a PIA packet from a client, it will fully trust the ENL header which includes a "ContentTransporter" type (ID / Index) and a length.
The function will try to fetch the content transporter by ID using <code>enl::TransportManager::getContentTransporter(unsigned char const &)</code>
Then it will try to dereference the pointer to call a virtual method: <code>virtual size_t readyReceiveStream(enl::RamReadStream&, enl::Buffer*, size_t)</code>

| nullptr dereference triggered by an invalid content transporter type in the ENL header (it will crash the game/process)
| Unknown
| Depends on the game

There's another one more interesting but it will have to wait a bit :)
