K is being oxidized,
Cu is being reduced

Explanation:

Since oxidation is the gain in oxidation state (loss of electrons), K is being oxidized because it has on oxidation state of 0 originally, and as the reaction proceeds, its oxidation state is raised to +1.

Since reduction is the lowering in oxidation state (gain of electrons), Cu is being reduced because it has on oxidation state of +2 originally, and as the reaction proceeds, its oxidation state is lowered to 0 from becoming pure Cu.
