  In this paper, we wish to investigate the weak cosmic censorship conjecture
(WCCC) for the non black hole object, Buchdahl star and test its validity. It
turns out that the extremal limit for the star is over-extremal for black hole,
$Q^2/M^2 \leq 9/8 >1$; i.e., it could have $9/8 \geq Q^2/M^2 > 1$. By carrying
out both linear and non-linear perturbations, we establish the same result for
the Buchdahl star as well. That is, as for black hole it could be overcharged
at the linear perturbation while the result is overturned when the non-linear
perturbations are included. Thus WCCC is always obeyed by the Buchdahl star.
