Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复：输入子系统：ati_remote2 —— 修复设备属性处理程序中的类型混淆问题此前，和属性是通过在父级上注册的。当提交 b20d6bf8014b（"Input: ati-remote2 - 使用驱动核心来实例化设备属性"）将该驱动迁移至由驱动核心通过中的来管理这些属性时，属性被移动到了已绑定的设备上，但相应的和回调函数并未同步更新。这导致回调函数仍对一个属于的设备指针调用，从而生成了一个无效的指针。修复方案：在属性处理程序中直接使用来获取

Vulnerability Title

Input: ati_remote2 - fix type confusion in device attribute handlers

Source: CVE Program / CVE List V5

Vulnerability Description

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.
