      "title": "Input: sur40 - fix input device registration ordering",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: sur40 - fix input device registration ordering\n\nIn sur40_probe(), input_register_device() was previously called early before\nthe V4L2 video device and vb2_queue components were fully initialized. If\nuserspace opened the input device immediately upon registration, sur40_open()\nwould trigger and start the sur40_poll() worker thread. This worker thread\ninvokes sur40_process_video() and accesses the uninitialized vb2_queue\nstructure, leading to a data race and potential system crash.\n\nFurthermore, if V4L2 or video registration failed after input_register_device()\nsucceeded, the error path fell through to calling input_free_device() on a\nsuccessfully registered device instead of input_unregister_device(), corrupting\ninput core state.\n\nMove input_register_device() to the very end of sur40_probe(). This ensures\nthe V4L2 and video queue structures are fully initialized before polling can\nstart, and naturally resolves the error path bug since input_free_device()\nis now only called when input registration has not yet occurred.\n\nTo maintain strict LIFO (Last-In, First-Out) teardown ordering, also move\ninput_unregister_device() to the very beginning of sur40_disconnect(). This\nguarantees that the input polling worker thread is stopped before V4L2\nvideo components or control handlers are unregistered.",
