Luna-4 / Lunik-IV

On May 16 this year asteroid 2010 KQ was discovered by the Catalina Sky Survey but which later was shown to be an artificial object in orbit around the Sun.  Once it was evident it was not a natural body its designation was withdrawn and it was reassigned the original descriptor given to it by the CSS, namey RK252A5.

<...>

The best estimate of its nature is that it is associated with the failed
attempt to land Luna-4 (Lunik-IV) on the Moon.

My question is: Does anyone have information on the fate of the 4th stage
used to launch Luna-4 towards the Moon?  Thanks in advance.
