Static spherically symmetric scalar-field spacetimes with small scalar charge are linearly unstable to radial perturbations, giving numerical support for cosmic censorship in this class.
However, the stability against polar perturbations in the specific problem considered still needs a detailed analysis

Penrose hypothesis and instability of naked singularities in static spherically symmetric systems with scalar fields
