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…
Removal of a deprecated cryptographic primitive (SHA-1) from the firmware API surfaceReduction of attack surface and prevention of future misuse of a collision-vulnerable hashNo direct vulnerability patch or memory-safety bug is present in the diff
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…
Cryptographic key handling changed: public key is now supplied rather than derivedPotential reduction of key-mismatch risk if caller provides correct public keyNew null-pointer check added for static_public_key
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…
NULL pointer passed to memory-zeroing helper in cryptographic codeUndefined behavior in C standard library contractDefensive hardening in Noise protocol implementation
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…
Removal of long-term public key storage from internal handshake stateCaller-supplied output buffer for remote static public key reduces internal secret retentionError-path memzero of returned key material on failure
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…
Build-option mapping now lives in project.toml files, increasing the attack surface for supply-chain/build-configuration tamperingMakefile change automatically enables debug-link for PYOPT=0 debug buildsValidation added to reject storage_insecure_testing_mode in production builds
This commit only updates test data. It corrects the capitalization (checksum) of Ethereum addresses used in automated tests and refreshes the expected screen-shot hashes those tests compare against. There are no changes to the actual Trezo…
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…
Enables a previously disabled security/validation feature (entropy check) for a specific device modelAdds version-gated behavior to avoid errors on older firmwareDefensive hardening of wallet setup randomness verification
This commit is a routine cleanup that removes the old SCons build system files from the Trezor Core firmware repository. It deletes Makefiles, SConscripts, and related Python helper scripts, but does not change any firmware source code, cr…
This commit updates Trezor's embedded MicroPython interpreter from an older version to 1.28.0. It pulls in several upstream MicroPython bug fixes, including stricter buffer-size checks for converting integers to bytes, a new stack-safety A…
Synchronizes upstream MicroPython fixes that include buffer-size and stack-safety hardeningPrevents Ctrl+C interruption of frozen boot code, reducing denial-of-service/control-flow risk during bootFixes sys.stdout.buffer.write() return value, which could affect code relying on correct I/O semantics
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…
No security-relevant logic changes observedNo input validation changesNo memory safety bug fixes (e.g., no overflow, use-after-free, or uninitialized memory fixes)
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…
Refactor only: helper function renames with equivalent semanticsNew str helper adds UTF-8 validation; bytes helper does not validateNo input validation, length, or error-handling changes observed
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 is a routine build-system update for the Trezor firmware. It changes where the build process looks for the MicroPython cross-compiler binary (mpy-cross) and synchronizes a configuration header with newer MicroPython code. There…
This commit updates the Trezor firmware build system to use a newer MicroPython mechanism for tracking special memory pointers called 'root pointers.' It removes hard-coded lists of these pointers from configuration files and instead colle…
GC root pointer handling changedBuild system now auto-collects root pointers instead of hard-coding themRemoves manual MICROPY_PORT_ROOT_POINTERS lists
