In the Linux kernel, the following vulnerability has been resolved:
mm/mincore: handle non-swap entries before !CONFIG SWAP guard
mincore swap() also fields migration/hwpoison entries (and shmem
swapin-error entries), which can exist on !CONFIG SWAP builds when
CONFIG MIGRATION or CONFIG MEMORY FAILURE is enabled. The
!IS ENABLED(CONFIG SWAP) guard ran before the non-swap-entry early return,
so mincore pte range() can spuriously WARN and report these pages
nonresident on !CONFIG SWAP kernels.
Move the guard below the non-swap-entry check so only true swap entries
trip the WARN, and migration/hwpoison entries take the existing "uptodate
/ non-shmem" path.
