## Description

In the Linux kernel, the following vulnerability has been resolved:  HID: bpf: prevent buffer overflow in hid_hw_request  right now the returned value is considered to be always valid. However, when playing with HID-BPF, the return value can be arbitrary big, because it's the return value of dispatch_hid_bpf_raw_requests(), which calls the struct_ops and we have no guarantees that the value makes sense.
