In kmalloc_oob_krealloc_less, I think it is better to test the size2 boundary.
If we do not call krealloc, the access of position size1 will still cause out-of-bounds and access of position size2 does not. After call krealloc, the access of position size2 cause out-of-bounds. So, use size2 is more correctly.
