Unless Foundation got in contact with customers who bought the old ones and replaced those devices, then yes, there is a group of users using Passports containing the 608A chip.

I don't think this vulnerability is that big of an issue and here is why. Your wallet won't be vulnerable to remote manipulation and hacking. For someone to retrieve your data, they would need physical access to the device. They will have to take it apart and perform Double Laser Fault Injections on the chip. That requires a lab, equipment, and knowledge. You are unlikely to be the victim of a robbery where robber Joe will know what to do with the chip once he has it.

But even if the chip wasn't vulnerable to Laser Fault Injection, you should be looking to transfer your coins elsewhere as soon as possible. The time needed to prepare and perform the attack is the time when you should create a new wallet, generate a seed elsewhere, and move your coins from from the device that is no longer in your possession.
