空穴来风 (kòng xué lái fēng) — (set phrase) a rumor that may have some basis (original meaning); (set phrase, modern colloquial) an unfounded rumor; groundless talk

Literally 'wind from an empty cave' — originally a rumor that has some basis. In modern usage it usually means the opposite: a baseless rumor. So 这并非空穴来风 = 'this is not without foundation', but 别信,那是空穴来风 = 'don't believe it, it's groundless'.
