CONFIG_UBSAN_INTEGER_WRAP is 'default UBSAN', which is problematic for a couple of reasons.

The first is that this sanitizer is under active development on the compiler side to come up with a solution that is maintainable on the compiler side and usable on the kernel side. As a result of this, there are many warnings when the sanitizer is enabled that have no clear path to resolution yet but users may see them and report them in the meantime.
