kernel: HID: hid-goodix-spi: validate report size to prevent stack buffer overflow
    </Bugzilla>
    <CWE>CWE-120</CWE>
    <Details xml:lang="en:us" source="Mitre">
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.

    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in the Linux kernel's hid-goodix-spi driver. This vulnerability, a stack buffer overflow, allows a local attacker to provide an oversized report to the system. This can lead to a buffer overflow, potentially enabling the attacker to execute arbitrary code with elevated privileges or cause the system to crash, resulting in a denial of service.
