Part 4/7:
What makes this bug so interesting is that it exists at a level below the manufacturer's code. Typically, people place trust in brands like Netgear or Ubiquiti, but this vulnerability is present in the code provided by the system-on-a-chip (SoC) manufacturer, Mediatek. This means the bug can affect not only manufacturer-developed devices but also open-source router OSes like OpenWRT 19 and 21.
