You don't even necessarily need to cut the bowed stud completely through - if you can cut halfway, enough to weaken it, and force it into alignment with its neighbor, that would keep the assembly stronger.
As a matter of practice, it is always better to have butting sheets of drywall meet over one stud than attached to adjoining studs. If they turn out to have different humidity behavior, you can get the drywall joint buckling and cracking with every change of season, and there is no amount of tightening or screwing parts together that can stop it. I had that situation with a pair of floor joists in my finished basement and finally pretty much gave up on having the joint stay invisible.
