There exists an unchecked length field in UBoot. The U-Boot DFU
implementation does not bound the length field in USB DFU download setup
packets, and it does not verify that the transfer direction corresponds to
the specified command. Consequently, if a physical attacker crafts a USB
DFU download setup packet with a wLength greater than 4096 bytes, they
can write beyond the heap-allocated request buffer.
