CVE-2026-64367

Kernel memory corruption via oversized HID report

Published Jul 25, 2026 · Updated Jul 25, 2026

Stack buffer overflow in the Goodix SPI HID driver in Linux Kernel allows local users to corrupt kernel memory via a crafted hidraw ioctl. goodix_hid_set_raw_report() appends caller-controlled report data after an 11- or 12-byte header in a 128-byte stack buffer without checking the combined length. Reachability requires low-privilege local access to a hidraw node bound to this driver; an oversized SET_REPORT can crash the kernel or corrupt privileged kernel state.
