Saved you a click: they're reporting on a minor problem with iPhones where "A strong magnetic field can interfere with OIS and closed-loop AF" and then link to a Samsung patent trying to mitigate this problem.
Lens-position sensors respond to magnetic fields. If you place a magnet near these sensors, the magnetic field will interfere with or temporarily disable the sensors. This can degrade the sensors' accuracy and limit the range of movement available to the lenses. The camera will continue to take photos with other means of stabilisation but without the benefit of OIS and closed-loop AF.
Damn, it sure needed that scary title invocative of data loss and severe hardware damage are you fucking kidding. Garbage clickbait.
Edit: the Apple support article is published 22 January 2024, so real groundbreaking reporting here; the patent was published 14 May this year.
