We can see that if the IS_MMAPPED bit is set in the corrupted size field, glibc will call munmap_chunk, which internally checks that prev_size + size is page-aligned.

The chance that a corrupted prev_size + size value still ends up page-aligned is extremely small. In practice, if IS_MMAPPED is set, the process will almost certainly abort before we can make use of the corruption.
