On PAE systems with sufficiently large physical memory ranges, the subtraction result of res->end - i + 1 can overflow when casted to size_t, resulting in is being set to 0 and causing an endless loop. This can hang or crash the kernel. See-also: 504ensicsLabs#36 Co-authored-by: Fabio Pagani <[email protected]>
