No, it isn't. CANBUS is a non-safe protocol ("black channel" in safety parlance) and if anything safety-relevant is sent over it, there is a safety protocol on top.

Black channel schemes are not resistant to malicious input unless security was intentionally built in. Safety and security are separate (but related) concerns. Besides, white channel is still (unfortunately) a thing in some parts of the industry.
