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

AI analysis · Low 30/100

This commit is a small defensive cleanup in Trezor's user-interface code. It adds a runtime check that prevents two UI features—'info' and 'external_menu'—from being used at the same time, because that combination is not implemented. It also removes two places in Python code that accidentally passed both flags together. The change makes a previously silent debug-only assertion into an explicit error, which helps avoid unexpected UI behavior rather than fixing an active security vulnerability.

This commit removes several internal 'debug' flags from normal production builds of the Trezor firmware and keeps them only in builds that have the optional 'ui_debug' feature enabled. These flags are used by automated tests (debuglink) to navigate menus and identify cancel buttons; they do not directly control security checks. The change reduces the chance that test-only state could accidentally affect or leak information in production firmware, but it is a cleanup rather than a fix for an active vulnerability.

This commit adjusts linker scripts that control how the Trezor hardware wallet's bootloader and security monitor (secmon) binary images are laid out in flash memory. It reduces alignment padding from 512 bytes to 4 bytes and changes how unused space at the end of each image is filled with zeros. The change appears to be a correctness fix for image padding rather than a fix for an exploitable memory corruption bug, but the exact security implications are not stated by the vendor.

AI analysis · Low 33/100

This commit changes how many wrong PIN attempts are allowed on Trezor hardware wallets that use a component called Tropic. Previously, devices using both Tropic and Optiga security chips were limited to 10 PIN attempts, while devices using only Tropic were allowed 16. The change makes all Tropic-based devices use 10 attempts, matching the stricter limit. This is a defensive consistency fix, not an active vulnerability patch, but it reduces the attack surface for PIN brute-force attempts on Tropic-only devices.

AI analysis · Informational 20/100

This commit adds Rust wrappers around existing low-level cryptographic functions in the Trezor firmware so they can be used by a new feature called THP. It does not appear to fix a known bug or vulnerability. The changes are mostly a refactor: they expose AES-GCM, Curve25519, HMAC-SHA256, SHA-512, CRC32, and a random-byte helper to Rust code, and add unit tests. There is no direct evidence in the commit that this resolves a security issue, but any new crypto binding introduces a small chance of misuse or memory-safety mistakes.

AI analysis · Low 30/100

This commit fixes a compiler-specific alignment definition for AES cryptographic data structures. Previously, the code only forced memory alignment when compiled with GCC on 64-bit x86, but not when compiled with Clang on the same architecture. The change makes Clang behave the same way as GCC, ensuring the AES context has the same memory layout regardless of which compiler is used. This is a hardening/fix for consistency in cryptographic code, but the commit message does not describe an active exploit or security vulnerability.

This is a routine dependency update for the Rust build tool bindgen inside Trezor firmware. It bumps bindgen from version 0.62.0 to 0.72.1 and adjusts the code to match the newer API. The change removes a small workaround that forced a function signature to be read as non-const pointers, because the newer bindgen now generates the correct const pointers. There is no direct security fix here, but keeping build tools current reduces the chance of future bugs or build issues.

AI analysis · Low 42/100

This commit fixes a bug in the Trezor hardware wallet's THP (Trezor Host Protocol) communication code. Previously, if the final acknowledgment (ACK) from the computer/app was lost, the device would not properly advance its internal sequence bit. This could cause the next message to use the wrong sequence number, potentially confusing the host software (Trezor Suite) and disrupting communication. The fix ensures the sequence bit is always advanced after a write attempt, even if the ACK is lost or the write is blocked.

This commit only changes a test command in the build Makefile. It wraps an emulator sanity check with a 10-second timeout so automated tests don't hang indefinitely if the emulator fails to start. There is no change to firmware code, cryptography, device behavior, or anything users interact with.

test(core): fix `test_autolock_cancels_ui` on T3W1

Otherwise, it will fail due to timeout (since the device suspends on autolock).

This is a test-only change that adds a device wake-up step for one specific Trezor model (T3W1) in an automated test. It does not modify the firmware or any production code, so it has no direct security impact on users.

This commit changes an automated GitHub workflow so that translation-sync pull requests are created using a dedicated bot account's token instead of the repository's default GitHub token. It also adds one employee as the assignee and reviewer. The change is a CI hardening/fix, not a vulnerability in the Trezor firmware itself. There is no direct evidence in the commit that this fixes an active security issue, but using a scoped bot token is generally safer than the default token because it limits what the workflow can do.

feat(core): disable stack protector in syscall stubs

[no changelog]

62/100 · AdequateMessage clarity
✓ Specific, descriptive subject✓ Names a concrete action or component✓ Uses a recognizable type or scope! No meaningful explanatory body
AI analysis · Low 26/100

This commit changes a low-level firmware file that handles system calls on Trezor hardware wallets. It disables the compiler's stack protector (a safety feature that helps detect certain memory corruption bugs) specifically in the 'syscall stubs' code. The commit message frames this as a feature and does not explain why the protector is being disabled or claim any security benefit. On its own, disabling a security mitigation is a security signal, but the diff is too small to determine whether this introduces a real vulnerability or is a necessary workaround for a technical constraint.

feat(core): improve applet mpu reconfig

AI analysis · Low 41/100

This commit reworks how the Trezor Core firmware configures the memory protection unit (MPU) when switching to small helper programs called applets. It adds a dedicated thread-local storage (TLS) region for applets and fixes a bug where region 4 was being configured from the wrong layout field (code2 vs data2). The changes are framed by the developer as an improvement, not a security fix, and no external security references are provided.

feat(core): add support for rwpi in applets

[no changelog]

AI analysis · Low 25/100

This commit adds plumbing for a new hardware feature called RWPI (Read-Write Position Independent code) in small helper programs ('applets') running on Trezor devices. It stores a 'static base' address in each task and sets register r9 when starting an applet. The change itself is a feature addition, not a visible bug fix, and there is no direct evidence in the commit that it fixes a security vulnerability. It may be defensive groundwork for safer dynamic app loading, but that is speculative.
