CVE-2024-27007
Disclosure Date: May 01, 2024 (last updated May 01, 2024)
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: change src_folio after ensuring it's unpinned in UFFDIO_MOVE
Commit d7a08838ab74 ("mm: userfaultfd: fix unexpected change to src_folio
when UFFDIO_MOVE fails") moved the src_folio->{mapping, index} changing to
after clearing the page-table and ensuring that it's not pinned. This
avoids failure of swapout+migration and possibly memory corruption.
However, the commit missed fixing it in the huge-page case.
