The HID core caps report size at\nHID_MAX_BUFFER_SIZE (16384) by default, while the driver does not set\nhid_ll_driver.max_buffer_size and performs no bounds checking before\ncopying the payload:\n\n    memcpy(tmp_buf + tx_len, buf, len);\n\nA hidraw SET_REPORT ioctl with a report larger than ~116 bytes\noverflows the stack buffer.\n\nAdd a size check after constructing the header, rejecting reports that\nwould exceed the buffer capacity.\n\nDiscovered by Atuin - Automated Vulnerability Discovery Engine."
