What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: platform/x86: asus-wireless: Fail probe when there is no ACPI match Every platform driver can be forced to match a device that does not match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device ACPI companion object need to verify its presence. asus_wireless_probe() returns success when acpi_match_acpi_device() finds no match, leaving behind an input device that never reports anything because the notify handler is not installed. Worse, when the driver is force-bound to a device without an ACPI companion, probe still succeeds and stores a NULL companion pointer, which asus_wireless_remove() later passes to acpi_dev_remove_notify_handler(), leading to a NULL pointer dereference on unbind. Return -ENODEV when the device does not match the ID table. This also covers the missing-companion case, because acpi_match_acpi_device() rejects a NULL device. Perform the check before allocating any driver state, instead of after the input device has already been registered.
