CVE-2026-63908

Input: atmel_mxt_ts - fix boundary check in mxt_prepare_cfg_mem

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

Input: atmel_mxt_ts - fix boundary check in mxt_prepare_cfg_mem

When a configuration file provides an object size that is larger than the
driver's known mxt_obj_size(object), the driver intends to discard the
extra bytes.

The loop iterates using for (i = 0; i < size; i++). Inside the loop, the
condition to skip processing extra bytes is:

    if (i > mxt_obj_size(object))
        continue;

Since i is a 0-based index, the valid indices for the object are 0 through
mxt_obj_size(object) - 1.

When i == mxt_obj_size(object), the condition evaluates to false, and the
code processes the byte instead of discarding it.

This causes the code to calculate byte_offset = reg + i - cfg->start_ofs
and writes the byte there, overwriting exactly one byte of the adjacent
instance or object.

Update the boundary check to skip extra bytes correctly by using >=.
