CVE-2024-52319: mm: use aligned address in clear_gigantic_page()
Description
In the Linux kernel, the following vulnerability has been resolved:
mm: use aligned address in clear_gigantic_page()
In current kernel, hugetlb_no_page() calls folio_zero_user() with the
fault address. Where the fault address may be not aligned with the huge
page size. Then, folio_zero_user() may call clear_gigantic_page() with
the address, while clear_gigantic_page() requires the address to be huge
page size aligned. So, this may cause memory corruption or information
leak, addtional, use more obvious naming 'addr_hint' instead of 'addr' for
clear_gigantic_page().
