Needs to be counter flashed. When I was building I'd take a 2x6 or 2x8 depending on the height of the step flashing above the roof and lay the 2x6 on edge on the roof along the side of the chimney. Then with a diamond blade in a circular saw gut a parallel to the roof groove about 1+ inches into the masonry using the 2x6 as a guide.

Then fabricate a piece of copper or lead coated copper counter flashing in a brake and with metal scissors, make sure it fit then apply masonry cement or silicon into the groove and install the counter flashing over the step flashing.

What you call a gable is actually known as a "cricket" at least in these parts it is.
