  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: magicmouse: Do not crash on missing msc-\u003einput\n\nFake USB devices can send their own report descriptors for which the\ninput_mapping() hook does not get called.  In this case, msc-\u003einput stays NULL,\nleading to a crash at a later time.\n\nDetect this condition in the input_configured() hook and reject the device.\n\nThis is not supposed to happen with actual magic mouse devices, but can be\nprovoked by imposing as a magic mouse USB device.",
