Benzema told team-mate Mendy not to pass to the Brazil international during half-time in their 2-2 draw with Borussia Monchengladbach on Tuesday.
Zidane insisted the incident showed his side are “alive and in the moment”.
“The most important thing is that it’s cleared up and that the players sort it out themselves. You say a lot of things on the pitch, but it always stays there,” Zidane added.
The Spanish champions had struggled in the first half of their Champions League group game against their German opponents, trailing to Marcus Thuram’s first of the evening.
Real Madrid were 2-0 down as late as the 87th minute before goals from Benzema and Casemiro rescued a point.
Zidane confirmed that France international Benzema and Vinicius had both trained alongside each other on Thursday.
“They spoke and that’s that,” said the Real boss.
“This kind of thing happens all the time on the pitch, things get heated. You say things about yourself, others and even me.”
