Every captured commit receives deterministic security triage and a separate communication-quality score. Security candidates and broader second-pass signals receive full-patch Ollama analysis.
Message quality measures whether a commit identifies its scope, purpose, rationale, testing, and supporting references. It does not change the security-severity score.
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…

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

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.
This commit simply renames two groups of internal status labels (called enums) in the Trezor firmware's cryptographic code. The old names like WAITING_FOR_REQUEST1 were shared between two different parts of the code, so the developer gave …
This commit fixes three places in the Trezor firmware's cryptographic code where a memory-clearing function could be called with a NULL pointer. In practice, passing NULL to memzero is harmless on Trezor's platform (it does nothing), but i…

This commit is a build-system refactoring for Trezor firmware. It moves the mapping of command-line build options to Rust/cargo features out of hard-coded Rust logic and into per-project TOML files. It also adds a small change so debug bui…

This commit changes the Trezor Python library so that, when setting up a Trezor Model One (the original Trezor 1 device), it now performs an entropy check by default if the device runs firmware 1.13.1 or newer. Previously, the library only…

This commit is a simple code cleanup that replaces a common MicroPython string-creation pattern with a new helper function. It does not change what the code does, only how it is written. There is no security issue visible in the change.
This is a large but straightforward internal cleanup: the project switched from using the MicroPython `ubinascii` module's `hexlify`/`unhexlify` functions to the standard Python `bytes.hex()` and `bytes.fromhex()` methods. The change remov…
This commit is a routine code cleanup in the Trezor firmware's embedded MicroPython modules. It replaces an older, two-step object allocation pattern with a newer helper that allocates memory and sets the object type in one step. The chang…

This commit is a routine maintenance refactor. MicroPython removed its built-in 'utimeq' module, so Trezor copied the same code into its own firmware tree and renamed it to 'timeq'. There is no security bug being fixed and no new vulnerabi…
This is a code cleanup change in Trezor's firmware that swaps one MicroPython internal helper for another. It replaces calls that create byte or string objects from a vstr buffer with newer, purpose-built helpers. The commit message says t…

This commit is a routine internal cleanup that switches how Trezor's firmware defines built-in MicroPython object types. It replaces older, manually-written type structures with a newer macro provided by the upstream MicroPython project. T…
This commit is a straightforward internal code refactor. It adds a small C wrapper file so that Rust code can call two specific internal MicroPython functions that are declared as static/inline in headers. There is no user-facing change, n…

This commit expands the Trezor hardware wallet's ability to clearly display details for more Tron TRC20 token transfers on the device screen. Previously, only one test token was recognized; now a built-in list of popular tokens (like USDT, USDD, BTT, etc.) is shown with their proper names and decimal places when a user signs a transfer. This is a user-experience and safety improvement, not a fix for a known exploit.

This commit is a routine code cleanup: it creates a Tron-specific copy of some smart-contract constants that were previously borrowed from the Ethereum app, and updates the Tron signing code to use its own copy. There is no functional change to how transactions are validated or signed, and no security bug is fixed or introduced.

This commit is a routine synchronization of translated user-interface text strings for the Trezor hardware wallet firmware. It updates Czech, German, Spanish, French, and Portuguese translations, refreshes the cryptographic signature that verifies those translations, and updates the expected screen hashes used in automated UI tests. There is no code that handles secrets, cryptography, network communication, or user authorization, and nothing in the changes suggests a security vulnerability.

signing or wallet pathsecond-pass: security-sensitive path
AI analysis · Low 43/100
This update fixes a bug in Trezor hardware wallets when signing certain Ethereum token-approval transactions. Some legitimate DeFi transactions include extra data that the wallet did not expect, which previously caused the device to crash instead of signing. The fix makes the wallet fall back to a simpler, generic signing mode for these unusual transactions. It is a reliability/usability fix rather than a theft-of-funds vulnerability, but a crash could still be used to deny service or trick a user into a less safe workflow.

This update changes how Trezor handles one specific Solana instruction (SetComputeUnitLimit) so it can optionally accept a reference to another program account. Previously the device rejected or could not parse transactions that included this extra account reference, which is used by some services such as Jito. The change is a compatibility fix rather than a clear-cut security patch, but the prior strict parsing could have caused transaction failures or user confusion when signing legitimate Solana transactions.
