A lot is going to depend on the specific model and what else is going on on the pi. Kernel GPIO gives access to the entire set of defined GPIOs, some of which are used for other things --e.g. the serial console-- that shouldn't be messed with from user space. If you try to use those pins, 'undefined things' can happen. Things get even more complicated if there's a hat installed, as those too use various pins in ways that are specific to the particular hat. Bottom line, make a careful study of the GPIO allocation for the particular model of pi in use, then ensure that you are modifying only otherwise unused GPIOs.
