Security candidatefix(ethereum): render unoswap pools as raw bytesby Ioan Bizău · 295a9b15 · Mar 24, 2026 · 2 filesMessage 80 · StrongLow 37Details
Commit message · Ioan Bizău

fix(ethereum): render unoswap pools as raw bytes

The `pools` parameter is not an `uint256[]` like the clear signing
registry claims - that being just an optimization to save on gas fees
and keeping the compiler happy by compiling (no pun intended) more
information into a field. So the best we can do for now is to render the
field as a raw value.

AI analysis · Low 37/100

This commit fixes how Trezor displays details for certain 1inch cryptocurrency swap transactions. Previously, the device tried to interpret a parameter called 'pools' as a list of plain numbers, but it actually contains packed binary data. The change makes the device show the raw bytes as hexadecimal instead of trying to decode them as numbers. This is a display/clarity fix rather than a direct theft-of-funds bug, but mis-displaying swap details could in theory help an attacker trick a user into approving a malicious transaction.

AI analysis · Low 34/100

This commit is a code refactor that reorganizes how Trezor handles Ethereum transaction display logic. It splits existing code into new modules for 'clear signing' and staking, and changes how token amounts and addresses are formatted before being shown to the user. There is no direct evidence in the commit that this fixes a security vulnerability; it appears to be preparation for supporting a new Ethereum standard (ERC-7730). However, because it touches the code that decides what users see on screen before signing transactions, any bug introduced here could affect how clearly users understand what they are approving.

This commit adds human-readable labels for certain cryptocurrency swap transactions on Trezor hardware wallets.

This commit is a code cleanup that moves the on-screen confirmation flow for Ethereum 'clear signing' into the device's UI layout modules. It also adds a final summary screen showing the maximum transaction fee. There is no direct evidence of a security vulnerability being fixed; it appears to be a user-interface refactor. However, adding the fee summary screen is a security-relevant improvement because it gives users more complete information before they approve a transaction.

This commit only changes the protocol definitions (the message formats) used for listing WebAuthn resident credentials.

There is no actual implementation of the pagination logic in the firmware or host code in this commit, and nothing in the commit suggests a security vulnerability.

This commit fixes a memory corruption bug in the code that caches Bitcoin-style key derivation paths inside Trezor's cryptographic library. When a derivation path was too deep to be cached, the code could store the derived key under the wrong path label. Later, a wallet or app asking for a different deep path could receive the wrong private key, which could lead to sending funds to an attacker-controlled address or signing with the wrong key. The fix stops the cache from storing these too-deep paths, and a new test confirms the wrong-key behavior no longer happens.

This commit replaces pre-built bootloader binary files for several Trezor hardware wallet models and updates their recorded cryptographic hashes. The change is presented as a routine version bump from older bootloader versions to version 2.1.16.0. The actual code inside the new bootloader binaries cannot be inspected from this commit, and there is no statement that the update fixes a security problem. On its own, this is a normal maintenance action rather than evidence of a vulnerability.

This commit only updates the written changelog for Trezor legacy firmware version 1.14.1. It deletes three small draft changelog entries and adds their text to the published CHANGELOG.md file. No program code, firmware logic, or security behavior is changed. The security note about warning on long Ethereum data is a documentation of a prior change, not a new fix in this commit.

This update changes how older Trezor devices (the 'legacy' T1B1 model) display long Ethereum transaction data before signing. Previously, the device only showed one screen of data, which could hide malicious content appended later in the same transaction. Now it shows up to five pages of data, and if there is still more data left, it shows a clear warning telling the user that not all data can be viewed and to proceed with caution. This is a security improvement that reduces the chance of a user approving a transaction whose full contents they have not seen.

This commit updates the embedded QA (quality assurance) bootloader binaries and their recorded cryptographic hashes for five Trezor hardware wallet models. QA bootloaders are internal test artifacts, not the production bootloaders shipped to end users. There is no indication in the commit that this fixes or introduces a security vulnerability.
