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.

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].

This bootloader patch makes the device erase a special protected memory region (backup RAM) when the user enters a 'wipe code' to factory-reset the device.

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.

There is no direct security fix here; it is a feature that improves real-time status reporting.

AI analysis · Informational 19/100

This commit is a code-quality and accuracy improvement for how the Trezor firmware estimates how long PIN operations will take. It replaces a single coarse heuristic with finer-grained per-command timing estimates for the Optiga and Tropic secure chips, adds a helper that models the chip's security-event-counter throttling, and moves the estimate logic closer to the functions it describes. There is no direct security vulnerability being fixed; the change is about making progress-bar timing more accurate, which indirectly helps user experience and may make side-channel timing analysis slightly more predictable. The commit message says '[no changelog]' and does not claim to fix a security issue.

This commit changes how the Trezor hardware wallet's earliest startup code (boardloader and bootloader) uses internal memory on the T3B1 model. It shifts small data and uninitialized-memory sections from one RAM bank (AUX1_RAM) to another (MAIN_RAM), and slightly adjusts the size and start addresses of those RAM regions. The title says this is to 'use ECC SRAM'—memory with built-in error-correction, which is a reliability/hardening improvement, not a vulnerability fix. There is no direct evidence in the commit of a security bug being patched.

cryptography-sensitive pathboot or update path
AI analysis · Moderate 63/100

This commit removes a special firmware memory section called ".confidential" that was meant to keep sensitive data (like cryptographic keys and seed-derived values) separate from ordinary memory. Previously, variables marked with a CONFIDENTIAL attribute were placed in this dedicated RAM region and copied from flash at startup. The patch deletes that whole mechanism across all Trezor models and instead marks sensitive local variables with a new LOCAL_CONFIDENTIAL macro. On the legacy build this still maps to the old behavior, but on the modern STM32 builds it effectively becomes a no-op, meaning those sensitive buffers now live in normal RAM/data sections. The change is presented as a cleanup, but it reduces a defense-in-depth isolation feature and could make it easier for a successful attacker to locate or extract secret material in memory.

This commit is a straightforward internal code cleanup for the T3W1 hardware wallet's on-device menu. It changes how menu choices are represented behind the scenes (from unique object tokens to plain integer codes) and reorganizes the Python handler code into smaller functions. There is no indication this fixes a security bug or introduces a new vulnerability.

This commit changes how Trezor stores wallet backup words (mnemonics) for Cardano support. It now keeps an extra binary copy of the mnemonic in device storage, separate from the encrypted text version. The change is described as a feature, not a security fix. It does not appear to introduce an obvious remote exploit, but it does add a new storage location holding sensitive seed material and includes a debug-only option that lets invalid mnemonics be loaded without raising an error.

This commit only adds a new automated test to the Trezor firmware test suite. It checks that Cardano public keys and addresses stay the same before and after a firmware upgrade that migrates internal app storage from version 2 to the current version. There is no change to the actual firmware code, wallet logic, or security behavior.

This commit only updates Cardano unit tests to convert text seed phrases into binary format before passing them to a cryptographic function. It does not change any production wallet code, user-facing behavior, or security-sensitive logic. There is no indication this fixes or introduces a vulnerability.

AI analysis · Informational 18/100

This commit simply fills in a previously empty placeholder with the real production public key used to verify signed payment requests. By itself, it is a routine configuration/key-installation change, not an exploitable vulnerability. The only security-relevant observation is that before this commit, payment-request signatures using this key could not have been validated, so the feature would not have worked in production.

This commit removes the 'experimental' label from two Trezor firmware features: PaymentRequest (used in several cryptocurrency transaction flows) and GetNonce (a random-number request). It also updates generated code and tests accordingly. The change itself is a feature graduation, not a fix for a known security bug. There is no direct evidence in the commit that it patches an active vulnerability, but it does widen the audience for these features by removing the experimental opt-in requirement.

AI analysis · Informational 15/100

This commit is a straightforward internal code cleanup: it splits one Python/C function that handled three different reboot behaviors into three separate, clearly named functions. There is no change to what the device actually does during a reboot or firmware upgrade, and no security bug is introduced or fixed.
