## Overview

In the Linux kernel, the following vulnerability has been resolved:

HID: hid-goodix-spi: validate report size to prevent stack buffer overflow

goodix_hid_set_raw_report() builds a protocol frame in a 128-byte stack
buffer (tmp_buf), writing an 11-12 byte header followed by the
caller-supplied report data.  The HID core caps report size at
HID_MAX_BUFFER_SIZE (16384) by default, while the driver does not set
hid_ll_driver.max_buffer_size and performs no bounds checking before
copying the payload:

    memcpy(tmp_buf + tx_len, buf, len);

A hidraw SET_REPORT ioctl with a report larger than ~116 bytes
overflows the stack buffer.

Add a size check after constructing the header, rejecting reports that
would exceed the buffer capacity.
