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().
