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 code cleanup (refactor) for the cryptographic handshake code used in Trezor devices. It changes how the other party's long-term public key is returned to the caller: instead of storing it inside an internal state structure…

This commit is a straightforward internal refactor of the Trezor firmware build tool's command-line argument handling. It changes many on/off flags from plain booleans to optional booleans so they can explicitly be set to true, false, or l…

This is a tiny code cleanup commit that replaces two calls to `ptr::null()` with Rust's `unwrap_or_default()` to silence automated Clippy lint warnings. It does not change what value is produced (still a null pointer when no salt is provid…
This commit is a straightforward internal code cleanup in Trezor's build tooling. It moves a data structure and two helper methods from one Rust source file to another and updates callers accordingly. There is no change to user-facing beha…
This commit only adds documentation. It updates the table of contents and adds a new markdown page plus a diagram explaining the project's 'xtask' build helper. No code, build scripts, or firmware logic was changed, so it cannot introduce …
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 fixes a filename-renaming step in the project's automated nightly build pipeline. It ensures ARM64 emulator files get the correct name expected by another testing tool. There is no change to the actual Trezor firmware code, dev…
This is a routine housekeeping change to reduce clutter in Git's status output for a third-party component (the MicroPython submodule). There is no indication it changes any code that runs on the Trezor device or affects security.

This update fixes a bug where a Trezor hardware wallet with SD-card protection enabled could not be locked if no PIN was set. The device should be lockable whenever SD protection is active, because the SD card itself acts as a security factor. The change makes the homescreen use a broader 'can lock' check instead of only checking whether a PIN is configured. A new automated test also verifies that pressing and holding the screen can lock the device in this configuration.

AI analysis · Low 49/100
This commit replaces internal programming assertions (which crash the device if they fail) with proper error handling for Ethereum transaction signing when a payment request is involved. It ensures that if someone supplies a payment request verifier, the transaction must have zero data bytes and must actually include a payment request object. Without the fix, a malformed or unexpected input could trigger an assertion failure instead of a clean error, potentially causing the device to crash or behave unpredictably during signing.

This commit fixes a build configuration issue so that debug builds of Trezor firmware, bootloader, and production-test firmware automatically enable a visual 'ui_debug_overlay' feature. That feature displays a small red square marker in the top-right corner of the screen, making it obvious when a debug/non-production build is running. It is a UI/UX and build-system change, not a fix for an exploitable security vulnerability.

This commit adds a new helper script that lets developers check whether a signed Trezor firmware file truly matches its unsigned counterpart and whether its digital signature is valid. It is a defensive verification tool, not a fix for a security flaw, and introduces no vulnerability in the device code itself.

This commit is a feature addition to Trezor's internal production-test firmware. It replaces generic string-based error messages with a structured, numbered error-code system. There is no direct security vulnerability being fixed or introduced; it is a maintainability and diagnostics improvement for factory testing tools.

This is a small maintenance update to Trezor's Ethereum clear-signing definitions for the LiFi cross-chain swap service. It adds alternative contract addresses for LiFi on four blockchains where the service uses a different address than usual, and tweaks a few on-screen labels (for example changing 'Recipient' to 'Receiver' and adjusting capitalization). There is no indication of a security vulnerability being fixed.
