commit fd97e4ad6d3b0c9fce3bca8ea8e6969d9ce7423b upstream. In do_adb_query() function of drivers/macintosh/adb.c, req->data is copied form userland. The parameter "req->data[2]" is missing check, the array size of adb_handler[] is 16, so adb_handler[req->data[2]].original_address and adb_handler[req->data[2]].handler_id will lead to oob read.
