CVE-2026-64367

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> HID: hid-goodix-spi: validate report size to prevent stack buffer overflow<br /> <br /> goodix_hid_set_raw_report() builds a protocol frame in a 128-byte stack<br /> buffer (tmp_buf), writing an 11-12 byte header followed by the<br /> caller-supplied report data. The HID core caps report size at<br /> HID_MAX_BUFFER_SIZE (16384) by default, while the driver does not set<br /> hid_ll_driver.max_buffer_size and performs no bounds checking before<br /> copying the payload:<br /> <br /> memcpy(tmp_buf + tx_len, buf, len);<br /> <br /> A hidraw SET_REPORT ioctl with a report larger than ~116 bytes<br /> overflows the stack buffer.<br /> <br /> Add a size check after constructing the header, rejecting reports that<br /> would exceed the buffer capacity.<br /> <br /> Discovered by Atuin - Automated Vulnerability Discovery Engine.
