Description
In the Linux kernel, the following vulnerability has been resolved:
HID: magicmouse: Do not crash on missing msc->input
Fake USB devices can send their own report descriptors for which the
input_mapping() hook does not get called. In this case, msc->input stays NULL,
leading to a crash at a later time.
Detect this condition in the input_configured() hook and reject the device.
This is not supposed to happen with actual magic mouse devices, but can be
provoked by imposing as a magic mouse USB device.
