  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: alps: unregister DualPoint Stick input device on remove\n\nalps_input_configured() allocates a second input device (\"DualPoint\nStick\") with input_allocate_device() and registers it, but the\nalps_driver struct has no .remove handler and input2 is not tracked in\nhdev-\u003einputs.  The default remove path (hid_hw_stop -\u003e hidinput_disconnect)\nonly iterates hdev-\u003einputs, so input2 is never unregistered and leaks\non every device removal.\n\nAdd a .remove handler that stops the device first (preventing URB\ncallbacks from touching input2 during teardown) and then unregisters\ninput2.",
