In the Linux kernel, the following vulnerability has been resolved:
mm/zone device: do not touch device folio after calling ->folio free()
The contents of a device folio can immediately change after calling
->folio free(), as the folio may be reallocated by a driver with a
different order. Instead of touching the folio again to extract the
pgmap, use the local stack variable when calling percpu ref put many().
