CVE-2026-64367

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

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

goodixhidsetrawreport() builds a protocol frame in a 128-byte stack buffer (tmpbuf), writing an 11-12 byte header followed by the caller-supplied report data. The HID core caps report size at HIDMAXBUFFERSIZE (16384) by default, while the driver does not set hidlldriver.maxbuffersize 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.
