The returned pointer is later\nused as a full firmware interface structure, so accepting an address near\nthe end of the shared section can still lead to out-of-bounds accesses.\n\nPass the expected object size to iface_fw_to_cpu_addr() and reject ranges\nthat do not fit entirely in the shared section.",
