CVE-2021-47214
CVE-2021-47214 affects Linux kernel hugetlb/userfaultfd handling. The fix corrects reservation restoration on userfaultfd error in hugetlb_mcopy_atomic_pte() by treating the is_continue path like pagecache insertion and altering the new_pagecache_page flag (renamed to page_in_pagecache) so restor...
