CVE-2026-64276 is an out-of-bounds memory-access vulnerability in the Linux kernel Synaptics RMI4 F30 input-driver handler. The rmi_f30_map_gpios() function allocated gpioled_key_map for at most six entries using min(gpioled_count, TRACKSTICK_RANGE_END), while rmi_f30_attention() dereferenced the map across the device-reported gpioled_count, which may range from 0 to 31. The driver also set input->keycodemax to the full reported count despite input->keycode referring to the smaller allocation. The corrected implementation allocates the keymap for the complete reported GPIO/LED count while continuing to assign supported mappings only within the trackstick range.
