In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a very large amount of data (including the whole stack) while reading a crafted ext4 filesystem.

Weakness

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
