"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: processor: Fix NULL-pointer dereference in acpi_processor_errata_piix4()\n\nIn acpi_processor_errata_piix4(), the pointer dev is first assigned an IDE\ndevice and then reassigned an ISA device:\n\n dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB, ...);\n dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB_0, ...);\n\nIf the first lookup succeeds but the second fails, dev becomes NULL. This\nleads to a potential null-pointer dereference when dev_dbg() is called:\n\n if (errata.piix4.bmisx)\n dev_dbg(&dev->dev, ...);\n\nTo prevent this, use two temporary pointers and retrieve each device\nindependently, avoiding overwriting dev with a possible NULL value.\n\n[ rjw: Subject adjustment, added an empty code line ]"
