The short version

What changed, and why it matters

This firmware update changes how the Keystone hardware wallet stores and checks device passwords. Previously, the device kept a separate password hash page in its secure element (SE) storage. After this update, password verification is done by trying to decrypt the actual account secret using the password, and the old password hash pages are wiped. The change also removes hard assertions on SE operations so that failures return error codes instead of crashing, and it maps a specific secure-element authentication failure to a wrong-password error. The version number is bumped from 12.4.6 to 12.5.0.

Recommended action

Treat this as a security-hardening and potential security-fix release. Users should upgrade to firmware 12.5.0 when available. Developers should verify that the legacy password hash wipe does not brick devices with partially written SE pages and that the new authentication error mapping does not leak information through timing or error counts.

Security signals we found

01

Removal of stored password hash page and migration to secret-decryption password verification

02

Addition of legacy password hash wipe routine on boot

03

SE error codes propagated instead of asserted, improving fault handling

04

ATCA_CHECKMAC_VERIFY_FAILED mapped to authentication error

05

UI loading overlay added during password verification to prevent repeated UI-driven attempts
