Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm: use aligned address in clear_gigantic_page()<br /> <br /> In current kernel, hugetlb_no_page() calls folio_zero_user() with the<br /> fault address. Where the fault address may be not aligned with the huge<br /> page size. Then, folio_zero_user() may call clear_gigantic_page() with<br /> the address, while clear_gigantic_page() requires the address to be huge<br /> page size aligned. So, this may cause memory corruption or information<br /> leak, addtional, use more obvious naming &amp;#39;addr_hint&amp;#39; instead of &amp;#39;addr&amp;#39; for<br /> clear_gigantic_page().
