In the Linux kernel, the following vulnerability has been resolved:

Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count

rmi_f30_map_gpios() allocates gpioled_key_map with

min(gpioled_count, TRACKSTICK_RANGE_END) == at most 6 entries, but

rmi_f30_attention() iterates the full f30->gpioled_count (device query

input->keycodemax is set to the full gpioled_count while input->keycode

points at the 6-entry allocation.

A device that reports gpioled_count > 6 with GPIO support enabled

therefore causes an out-of-bounds read on the attention interrupt and

out-of-bounds read/write through the EVIOCGKEYCODE/EVIOCSKEYCODE ioctls,

which bound the index only against keycodemax. This is the same defect

as the F3A handler, which was copied from F30.

Size the keymap for the full gpioled_count; the mapping loop still

assigns only the first min(gpioled_count, TRACKSTICK_RANGE_END) entries. (NVD)
