- Summary
- mm/zone_device: do not touch device folio after calling ->folio_free()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mm/zonedevice: do not touch device folio after calling ->foliofree()
The contents of a device folio can immediately change after calling ->foliofree(), 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 percpurefputmany().
