  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: NFIT: core: Fix acpi_nfit_init() error cleanup\n\nIf acpi_nfit_init() fails after adding the acpi_desc object to the\nacpi_descs list, that object is never removed from that list because\nthe acpi_nfit_shutdown() devm action is not added for the NFIT device\nin that case.  Next, the acpi_nfit_init() failure causes\nacpi_nfit_probe() to fail, the acpi_desc object is freed, and a\ndangling pointer is left behind in the acpi_descs.  Any subsequent\nACPI Machine Check Exception will trigger nfit_handle_mce() which\niterates over acpi_descs and so a use-after-free will occur.\n\nMoreover, if acpi_nfit_probe() returns 0 after installing a notify\nhandler for the NFIT device and without allocating the acpi_desc\nobject and setting the NFIT device's driver data pointer, the\nacpi_desc object will be allocated by acpi_nfit_update_notify()\nand acpi_nfit_init() will be called to initialize it.  Regardless\nof whether or not acpi_nfit_init() fails in that case, the\nacpi_nfit_shutdown() devm action is not added for the NFIT device\nand acpi_desc is never removed from the acpi_descs list.  If the\nacpi_desc object is freed subsequently on driver removal, any\nsubsequent ACPI MCE will lead to a use-after-free like in the\nprevious case.\n\nTo address the first issue mentioned above, make acpi_nfit_probe()\ncall acpi_nfit_shutdown() directly on acpi_nfit_init() failures and\nto address the other one, add a remove callback to the driver and\nmake it call acpi_nfit_shutdown().  Also, since it is now possible to\npass NULL to acpi_nfit_shutdown() or the acpi_desc object passed to it\nmay not have been initialized, add checks against NULL for acpi_desc and\nits nvdimm_bus field to that function and make acpi_nfit_unregister()\nclear the latter after unregistering the NVDIMM bus.",
