Description
A vulnerability in the Linux kernel's logitech-hidpp driver could cause a kernel crash when processing USB HID report descriptors that define report structures without valid fields. This issue arises because the function hidpp_get_report_length() did not properly check the maximum field count, allowing fake USB gadgets to trigger a crash by sending crafted HID report descriptors.
