Description

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