  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: asus-wireless: Fail probe when there is no ACPI match\n\nEvery platform driver can be forced to match a device that does not match\nits list of device IDs because of device_match_driver_override(), so\nplatform drivers that rely on the existence of a device ACPI companion\nobject need to verify its presence.\n\nasus_wireless_probe() returns success when acpi_match_acpi_device()\nfinds no match, leaving behind an input device that never reports\nanything because the notify handler is not installed.  Worse, when the\ndriver is force-bound to a device without an ACPI companion, probe\nstill succeeds and stores a NULL companion pointer, which\nasus_wireless_remove() later passes to acpi_dev_remove_notify_handler(),\nleading to a NULL pointer dereference on unbind.\n\nReturn -ENODEV when the device does not match the ID table.  This also\ncovers the missing-companion case, because acpi_match_acpi_device()\nrejects a NULL device.  Perform the check before allocating any driver\nstate, instead of after the input device has already been registered.",
