There has been a lot of sloppy reporting regarding DarkSword, with basically every news outlet saying that iOS 18 is vulnerable. It’s not, if you have the latest 18.7.3.
Google has a more in depth analysis, with a lot more information on the specific versions of iOS that are affected.
TL;DR It doesn’t seem to affect 18.7.3 at least (might also not work on 18.7.2 given that CVE-2025-43520, which DarkSword uses, has been patched in .2).
