find_next_bit and find_last_bit code operates on the unsigned long *addr, and without knowing the size of the actual buffer passed to it, Kasan detects it as invalid Out of Bound read access. find_next_bit and find_last_bit implementation is very generic and it need not to be modified for the Kasan, so we are skipping it from the sanitization. Following is the Kasan error log for the reference.
