The short version

What changed, and why it matters

This commit relaxes a version check so that Trezor devices can load translation (language) files even when the translation file's build number differs from the firmware's build number. Previously, the version had to match exactly, which could block users from changing languages after a small firmware update. The change still requires the major, minor, and patch version numbers to match, and it adds a check that the version field is exactly four parts long. There is no direct security vulnerability here; it is a usability fix.

Recommended action

No immediate action required. This is a benign usability fix. If reviewing for defense in depth, confirm that translation blobs remain signed and that the build-version field is not used for any security-critical decision elsewhere.

Security signals we found

01

Version check relaxation in a language-loading code path

02

New length validation before version comparison

03

No change to signature, hash, length, or magic validation

04

No mention of security impact in commit message or changelog

refactor(core): digest EIP-1559/EIP-7702 magic without RLP encoding

This commit is a small internal cleanup in Trezor's Ethereum signing code. It changes how two special 'magic' bytes (the transaction type markers for newer Ethereum transaction formats) are fed into the cryptographic hash. Previously the c…

test(core): test RLP self-encoding bytestrings

This commit only adds a new unit test to the Trezor firmware codebase. It verifies that very short Ethereum RLP-encoded byte strings and small positive integers encode to themselves, which is a known property of the RLP specification. No p…

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…
