NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

mm: use aligned address in copy_user_gigantic_page()

In current kernel, hugetlb_wp() calls copy_user_large_folio() with the fault address. Where the fault address may be not aligned with the huge page size. Then, copy_user_large_folio() may call copy_user_gigantic_page() with the address, while copy_user_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 copy_user_gigantic_page().
