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

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. This vulnerability occurs because the driver incorrectly allocates memory for a keymap, leading to an out-of-bounds memory access. A local user with access to a specially crafted input device could exploit this to read or write t...
