What is the Chandrasekhar-Friedman-Schutz (CFS) instability, exactly?

Hey!!!
In a rotating star, a non axially symmetric perturbation rotating slower than a star will radiate off angular momentum, thus increasing the size of the perturbation. Apparently, any rotating star is unstable in general relativity. Obviously, rotating stars do exist. Somehow, I think damping effects in an actual star work against the instability for slowly rotating stars, but can't fight the instability for fast rotating stars.
Thanks!!
