Some K glyphs use 壬 instead of 王

The characters "遑" and "隍" in Source Han Sans KR and Source Han Serif KR seem to be very strange with the "壬" at the bottom of "皇".

I think the character "潤" in Source Han Sans KR and Source Han Serif KR also seem to be strange with "壬" instead of "王"

For 潤 (U+6F64), this is not fixed as of Noto Serif v2.002. Please fix in the next version by simply remapping to the JP glyph for KR.
