Eh a month or two before the October 2023 Israel conflict - there were many reports of GPS jamming in the middle east impacting air transport aircraft. To the point where it basically caused various failure modes that shouldn't have happened with avionics (think the things you'd expect in a fuzzing scenario). It was pretty eye opening example of just how poor modern avionics are (and their integrations) when they get unpredictable inputs & the dependant downrange systems that rely upon that data.
