NEGLIGIBLE

A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to infinitely recurse, causing the stack to grow infinitely and eventually either crash or overwrite other data.

Weakness

The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
