ACPI: NFIT: core: Fix possible NULL pointer dereference
In the Linux kernel, the following vulnerability has been resolved: ACPI: NFIT: core: Fix possible NULL pointer dereference After commit 9b311b7313d6 ("ACPI: NFIT: Install Notify() handler before getting NFIT table"), acpi_nfit_probe() installs an ACPI notify handler for the NFIT device before checking the presence of the NFIT table. If that table is not there, 0 is returned without allocating the acpi_desc object and setting the driver data pointer of the NFIT device. If the platform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification on the NFIT device at that point, acpi_nfit_uc_error_notify() will dereference a NULL pointer. Prevent that from occurring by adding an acpi_desc check against NULL to acpi_nfit_uc_error_notify().
