In the Linux kernel, the following vulnerability has been resolved:HID: betop: fix slab-out-of-bounds Write in betop_probeSyzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.So this patch checks hid_device's input is non empty before it's been used.
