If packet_length exceeds 64 bytes, the memcpy operation overwrites the return address stored on the stack, allowing the attacker to redirect the Program Counter (PC) upon function return.

In short, “verified” here means: It works, reliably, on unpatched versions of Pico 300Alpha2 firmware v2.1.4 and earlier.
