Ledger Discloses Vulnerability: Displayed Parameters May Differ from Final Signed Parameters

This disclosure shifts the trust assumption for hardware wallet users: the device's core promise is that what you see is what you sign. If display and signed data can diverge, the attack surface broadens beyond remote exploits to include potential UI manipulation or middleware interference. The immediate impact is on advanced users and protocols relying on precise parameter verification, not casual transfers. The open question is whether Ledger's fix fully closes the gap or if this exposes a class of display-layer risks across other vendors, prompting broader scrutiny of hardware wallet security models.
