Yes; and it's quite disturbing that Lumen Gentium spouts this falsehood:
But the plan of salvation also includes those who acknowledge the Creator. In the first place amongst these there are the Muslims, who, professing to hold the faith of Abraham, along with us adore the one and merciful God, who on the last day will judge mankind.
It's also disturbing that many people think all promulgations of the Second Vatican Council are infallible.
With Islam, appeasement is the surest way to defeat! They do not respect it and will steamroll over those who suggest it.
The Vatican II Council would be part of the ordinary and universal magisterium. The OUM teaches infallibly. Therefore, assuming true authority was present, these teachings would be infallible.
