I’m not sure what your point was: that’s the same article Ars linked, with the same message and no additional information because, as the Ars writer noted, they’re withholding details until the vendors fix it.
No. He's saying that without the technical details, Ars is overblowing this issue. Maybe exploitation requires radio gear of $5k and being present next to the victim while their BLE is turned on. Without the details, you can't say if this is a big issue or just another overhyped Check Point research paper, as this company has a history of doing.
The Ars article includes the CVEs.
The technical details are withheld for the time being until (presumably) systems are patched. The Ars article includes the CVEs, which is all the technical detail that's currently available.
That doesn’t make any sense: he said to trust the researchers, but Check Point is saying nothing different. If the theory was the different one you’re offering, the advice would be not to trust the researchers.
Checkpoint does not say that just playing a video file can exploit these bugs.
