Where the fault address may be not aligned with the huge\npage size.  Then, copy_user_large_folio() may call\ncopy_user_gigantic_page() with the address, while\ncopy_user_gigantic_page() requires the address to be huge page size\naligned.  So, this may cause memory corruption or information leak,\naddtional, use more obvious naming 'addr_hint' instead of 'addr' for\ncopy_user_gigantic_page().\n\ud83d\udccf Published: 2025-01-11T12:35:38.375Z\n\ud83d\udccf Modified: 2025-01-11T12:35:38.375Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/cb12d61361ce769672c7c7bd32107252598cdd8b\n2. https://git.kernel.org/stable/c/f5d09de9f1bf9674c6418ff10d0a40cfe29268e1", "creation_timestamp": "2025-01-11T13:06:42.000000Z"}
