enable_best_rng() is used in hwrng_unregister() to switch away from the currently active RNG, if that is the one currently being removed. However enable_best_rng() might fail, if the next RNG's init routine fails. In that case enable_best_rng() will return an error code and the currently active RNG will remain active. After unregistering this might lead to crashes due to use-after-free. Fix this by dropping the currently active RNG, if enable_best_rng() failed. This will result in no RNG to be active, if the next-best one failed to initialize. This problem was introduced by |
