      "title": "HID: magicmouse: do not keep a stale msc->input if no input is claimed",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: magicmouse: do not keep a stale msc->input if no input is claimed\n\nmagicmouse_input_mapping() caches the first hid_input's input_dev in\nmsc->input while the report descriptor is parsed, and the rest of the\ndriver treats a non-NULL msc->input as proof that an input device was\nregistered.\n\nThat does not hold on the hid-input error path. If hidinput_connect()\nfails -- for instance because input_register_device() returns an error --\nit unwinds through hidinput_disconnect(), which frees every input_dev it\ncreated, including the one cached in msc->input.\n\nThe failure does not abort the probe. hid_connect() only skips the claim:\n\n\tif ((connect_mask & HID_CONNECT_HIDINPUT) && !hidinput_connect(hdev,\n\t\t\t\tconnect_mask & HID_CONNECT_HIDINPUT_FORCE))\n\t\thdev->claimed |= HID_CLAIMED_INPUT;\n\nand the \"device has no listeners\" bailout below it does not fire for this\ndriver, which sets ->raw_event; on the USB Magic Mouse 2 / Magic Trackpad\n2 paths hidraw and hiddev are claimed as well. hid_hw_start() therefore\nreturns 0 and magicmouse_probe() continues with msc->input pointing at\nfreed memory. Being non-NULL, it passes the \"input not registered\" check\nin probe and the NULL checks in ->raw_event and ->event, so the next\ninput report dereferences freed memory.\n\nClear msc->input when the HID core did not claim an input device, so the\nexisting NULL checks cover this case as well.",
