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.
Discovered by Atuin - Automated Vulnerability Discovery Engine.
