Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.12.95/6.18.38/7.1.3 and classified as very critical. Affected by this vulnerability is the function goodix_hid_set_raw_report of the component hid-goodix-spi. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2026-64367 since 07/19/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 09/04/2026).

Upgrading to version 6.12.96, 6.18.39, 7.1.4 or 7.2-rc1 eliminates this vulnerability. Applying the patch ad47ad624f2fce0bc44bbadb664242461a97d774/dae1d000ddfd5c2140b036e47fff0c497ae9c64b/835fcc8655569737e3f057d42875a96259db74c2/db0a0768d09273aadadeb76730cd658d720333a4 is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
