They won't be leaked, though. With a large western coompany like NXP, especially being that it's one with crypto-related business units, it's basically guaranteed that the keys will be in an HSM. There's always a slight chance they're inept and the private key is sitting in someone's home directory and they could decide to leak it, but in this case the chances seem very low.
Might have better luck with the Taiwanese hardware vendors - as I recall a major Taiwanese PC motherboard maker got hacked recently and UEFI secure boot keys were taken, so they probably weren't storing them in an HSM and don't have proper security practices in place for cryptographic material.
