Summary

In the Linux kernel, the following vulnerability has been resolved:

Input: ati_remote2 - fix type confusion in device attribute handlers

Previously, the channel_mask and mode_mask attributes were registered on the parent usb_device via sysfs_create_group(). When commit b20d6bf8014b ("Input: ati-remote2 - use driver core to instantiate device attributes") converted the driver to let the driver core manage them via dev_groups in struct usb_driver, the attributes moved to the bound usb_interface devices, but the show and store callbacks were not updated accordingly.

As a result, the callbacks still invoked to_usb_device() on a device pointer belonging to a struct usb_interface, producing an invalid usb_device pointer.

Use to_usb_interface() directly in the attribute handlers to obtain the interface and its driver data.
