    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/zone_device: do not touch device folio after calling ->folio_free()\n\nThe contents of a device folio can immediately change after calling\n->folio_free(), as the folio may be reallocated by a driver with a\ndifferent order.  Instead of touching the folio again to extract the\npgmap, use the local stack variable when calling percpu_ref_put_many().",
