[no changelog]

57/100 · ThinMessage clarity
✓ Descriptive subject✓ Names a concrete action or component✓ Uses a recognizable type or scope! No meaningful explanatory body
AI analysis · Moderate 57/100

This commit fixes a typo in the code that manages the Optiga secure chip's metadata. The code was writing a value to the wrong variable name (`metadata_locked` instead of `metadata`). Because the intended `metadata` structure was not fully initialized, the device might have compared stored secure-chip settings against an incomplete or incorrect expected value. In the worst case this could affect whether the device correctly detects that the Optiga chip is configured, which is part of the hardware-security boundary protecting secrets. The change is a one-line variable-name correction and is marked [no changelog], so the vendor does not describe it as a security fix.

AI analysis · Low 36/100

This commit removes a 'Go to bootloader' menu option from normal user builds of the Trezor hardware wallet, keeping it only in debug/developer builds. The change prevents an ordinary user from intentionally or accidentally rebooting the device into bootloader mode through the on-device menu. While entering bootloader mode is a normal part of firmware updates, exposing it in production builds could let a local attacker with brief physical access force the device into a state where they could attempt to install modified firmware or interfere with an update. The patch is narrow: it only hides the menu item behind a debug-only compile flag, so the underlying bootloader entry mechanism still exists for legitimate update workflows.

AI analysis · Low 44/100

This commit fixes a UI flow bug in the Trezor hardware wallet's 'Eckhart' layout. Previously, when a user opened a menu during a confirmation screen and chose an item, the wrong internal signal could be sent: the first menu item was always treated as 'Info' and the second as 'Cancel', even if the menu only contained a cancel option. The fix tracks which menu items actually exist and maps the user's selection to the correct result (Info or Cancel).

AI analysis · Informational 16/100

This commit fixes a build configuration issue for the Trezor T3W1 hardware wallet. The device supports reading a unique serial number, but the build system was not correctly advertising that capability. As a result, the Python module that handles the 'get serial number' command was accidentally excluded from the firmware image, so the feature would not work at runtime. The patch adds the missing capability flag for the T3W1 (emulator and three hardware revisions) and fixes a related list-concatenation bug in the build script that could have caused other feature exclusions to behave incorrectly. There is no direct evidence in the commit of a security vulnerability; it reads as a functionality/availability fix.

Commit message · Roman Zeyde

feat(core): show an explicit warning when `ButtonRequest` ACK is delayed

This should help the user to avoid the "blank screen" issue[1]
(if the layout is closed before `ButtonRequest` loop is done, the
user will see a blank screen - until a new message is received).

This PR doesn't allow the user to abort the layout task, since
it may leave the THP channel in a "non-writeable" state (if the
flow is aborted before `ButtonRequest` THP-level ACK is received,
ABP will prevent further writes into the channel[2].

AI analysis · Low 35/100

This commit changes the Trezor bootloader so that Bluetooth Low Energy (BLE) settings are remembered across reboots. Previously, the bootloader would turn BLE back on even if the user had turned it off. Now the bootloader reads a saved 'BLE enabled' flag from backup memory and only enables BLE if the user had left it on. The pairing/setup workflows still force BLE on because they need it. This is a privacy/usability fix rather than a critical security patch, but it prevents an unwanted BLE radio from being active when the user expects it to be off.

AI analysis · Informational 23/100

This commit moves a function call (unit_properties_init) so it runs earlier during the startup of a special factory-testing program called prodtest, instead of only when Bluetooth support is enabled. The change is in a low-level embedded file used during hardware production testing, not the normal wallet firmware users run. The commit message says it is a fix but gives no details about any security impact, and no independent security references were provided.

feat(core): prepare fuel gauge / battery model for different battery types

This commit refactors the Trezor firmware's battery fuel-gauge code so it can support multiple battery types in the future. It replaces hard-coded battery model constants with a runtime-selected structure based on a battery_type value read from device OTP memory. There is no obvious security bug in the diff, but the change introduces a new hardware-derived input (battery_type) into power-management calculations. Currently only battery type 0 is handled, and any unknown type falls back to the same default model.

This commit adds a way for the Trezor device to tell the connected computer or phone when its power source changes (for example, when USB is plugged in or a wireless charger is placed nearby). It also exposes two new status flags, usb_connected and wireless_connected, in the device's feature report. There is no direct security fix here; it is a feature that improves real-time status reporting.

AI analysis · Informational 15/100

This commit adds a new developer/testing tool that creates a fake Bluetooth (BlueZ) interface on a developer's computer. It lets software talk to a Trezor emulator as if the emulator were a real Bluetooth device. It is not a fix for a security issue and does not change any production firmware, wallet, or device code. It is purely a testing/development helper.

This commit is a code cleanup that moves emulator-only UDP socket handling for the Trezor hardware wallet emulator into a shared helper module. It affects only the Unix emulator build, not real Trezor devices. The change does not appear to fix or introduce a security vulnerability; it is a refactoring to reduce duplicated code between USB and BLE emulation layers.

AI analysis · Informational 21/100

This commit adds a software-only Bluetooth Low Energy (BLE) emulator for Trezor hardware wallets. It is a testing/development feature that lets a desktop emulator simulate BLE connections over local UDP network sockets. It does not change real hardware behavior and is not a security fix or a disclosed vulnerability. The main risk is that any emulator-only code could, in theory, contain bugs that affect testing environments, but there is no direct evidence this introduces an exploitable flaw in production devices.
