The short version

What changed, and why it matters

This commit is a documentation-only changelog update for the Trezor firmware release 2.12.5. It lists several security fixes that were already made in earlier code changes, including protections for Ethereum swaps and staking, Solana token display and stake lockup confirmation, and Stellar network and signer details. The commit itself does not change any firmware code, but it confirms that the vendor considers these items security-relevant for the release.

Recommended action

Treat this commit as a release-note artifact, not as a patch. Review the linked pull requests (#7140, #7310, #7487, #7544, #7582, #7652, #7678, and the security PRs for Ethereum/Solana/Stellar) to verify that the actual code mitigations are present and correct. Users should install firmware 2.12.5 to receive the security fixes described.

Security signals we found

01

Vendor labels six items under a 'Security' changelog section.

02

Ethereum: blocks native token transfers in SLIP-24 swaps and staking contexts, implying prior missing validation could have led to unintended value transfers.

03

Solana: previously hidden stake lockup settings are now shown for confirmation, reducing risk of locked funds.

04

Solana: ALT-referenced token accounts were displayed as lookup-table addresses instead of real mint/owner, a UI deception risk.

05

Stellar: network and signer weight details added to signing confirmation, reducing transaction/malleability confusion.

06

Commit is documentation-only; no code changes are present in the diff.
