The short version

What changed, and why it matters

This commit fixes how cryptocurrency addresses are visually grouped into chunks on Trezor device screens for several wallet models. Previously, addresses could be displayed with missing or incorrect spacing, which might make it harder for users to visually verify an address before approving a transaction. The fix changes the low-level text layout code and passes the chunking option through two user-interface layouts. It is a display/rendering bug fix rather than a cryptographic flaw, but because address verification is a key anti-phishing step, any display issue has security relevance.

Recommended action

Treat as a low-to-moderate security-relevant bug fix. Users should update firmware so that address chunking displays correctly, preserving the usability of address verification. No immediate incident response is required beyond normal patching, because the issue is in display formatting rather than signature verification or key management.

Security signals we found

01

UI display bug in address verification flow

02

Missing argument forwarding caused chunkification to be silently disabled on Bolt/Caesar layouts

03

Low-level text layout could overwrite or miscompose chunks

04

Fix is limited to rendering; no signing or secret-handling code changed

05

Vendor changelog entry labels it as a fix for address chunkification

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
