CVE-2025-68777
Input: ti_am335x_tsc - fix off-by-one error in wire_order validation
Description

In the Linux kernel, the following vulnerability has been resolved: Input: ti_am335x_tsc - fix off-by-one error in wire_order validation The current validation 'wire_order[i] > ARRAY_SIZE(config_pins)' allows wire_order[i] to equal ARRAY_SIZE(config_pins), which causes out-of-bounds access when used as index in 'config_pins[wire_order[i]]'. Since config_pins has 4 elements (indices 0-3), the valid range for wire_order should be 0-3. Fix the off-by-one error by using >= instead of > in the validation check.
