"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm: use aligned address in copy_user_gigantic_page()\n\nIn current kernel, hugetlb_wp() calls copy_user_large_folio() with the\nfault address. 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()."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: usar direcci\u00f3n alineada en copy_user_gigantic_page() En el kernel actual, hugetlb_wp() llama a copy_user_large_folio() con la direcci\u00f3n de error. Donde la direcci\u00f3n de error puede no estar alineada con el tama\u00f1o de p\u00e1gina enorme. Entonces, copy_user_large_folio() puede llamar a copy_user_gigantic_page() con la direcci\u00f3n, mientras que copy_user_gigantic_page() requiere que la direcci\u00f3n est\u00e9 alineada con el tama\u00f1o de p\u00e1gina enorme. Por lo tanto, esto puede causar corrupci\u00f3n de memoria o fuga de informaci\u00f3n. Adem\u00e1s, use un nombre m\u00e1s obvio 'addr_hint' en lugar de 'addr' para copy_user_gigantic_page()."
