In the wild as in "being actively exploited" yes, that's quite possible, but it's not a practical exploit for large-scale hacks on devices. The required firmware changes are likely to be somewhat different for each version of the radio hardware and firmware and each carrier's OS variants. That means that you'd either need a very sophisticated set of exploit code (which means complicated and bulky when you may not have a lot of space to play with and may be working in hand-optimized assembler) or that you need to narrow your focus to only specified handsets. Even after that, you then have to have a WiFi access point pushing this, so even if you're in a high-traffic area such as a city downtown or an airport you're going to impact a relatively small percentage of devices. If you have control of a large botnet of compromised WiFi routers you might be able to push this from those, but the more you do that the more likely you are to be discovered, and you're still going to have the problem of selectivity. What this all translates to is that exploiting this on a wide scale would require a lot of resources and extremely skilled developers while also being at fairly high risk of detection. Using this for highly targeted attacks on the other hand would allow for less work generalizing the attack and could probably go undetected. Further, if someone not a state actor has "weaponized" this their best option for making money on it would likely be to sell the exploit to either a government or to one of the groups who specializes in targeted hacking.
