When commit b20d6bf8014b\n(\"Input: ati-remote2 - use driver core to instantiate device\nattributes\") converted the driver to let the driver core manage them via\ndev_groups in struct usb_driver, the attributes moved to the bound\nusb_interface devices, but the show and store callbacks were not updated\naccordingly.\n\nAs a result, the callbacks still invoked to_usb_device() on a device\npointer belonging to a struct usb_interface, producing an invalid\nusb_device pointer.\n\nUse to_usb_interface() directly in the attribute handlers to obtain the\ninterface and its driver data.\n\n## Affected\n\n- `Linux >= b20d6bf8014b2d6fcf65c150453d95a6276fd1fa < e44ec6b6d3c0b8ea089b589fa0cce49a4da66b89`\n- `Linux >= b20d6bf8014b2d6fcf65c150453d95a6276fd1fa < d738e51bf2c21921df351f536147178ae3cbd38b`\n- `Linux >= b20d6bf8014b2d6fcf65c150453d95a6276fd1fa < 2caae9d1977beea0a7914b3d86639262801fd116`\n- `Linux >= b20d6bf8014b2d6fcf65c150453d95a6276fd1fa < f321cc430c49b6c1be0d53f2ef19d8342d8029cc`\n- `Linux 6.11`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
