Same software has same error? Likely to be a software problem. Might be OS or driver, but can't tell since no information provided.
Error description leads me to think that a previously dimensioned buffer is not being resized on demand and so the information intended to be stored is overriding the available size. This would be a 'bug'. It might be malware, too.
Suggest you locate KUMA forum. Ask if it is a known bug. Otherwise, run 'full scan', just in case something nasty is getting into your system. AND, as mentioned above..." Try reinstalling the game or updating it " (this is NOT the wrong answer, it just may not be the right one)..
