CoinBatmi feature visual — market neutral — Ledger patched an Ethereum app bug that could show one transaction and sign another
How critical was the vulnerability allowing Ledger's Ethereum app to display one transaction while signing another, prompting a recent security patch?
Ledger released version 1.22.2 of its Ethereum application, implementing two new signing-state safeguards to address a critical transaction display vulnerability. This update, published on 2026-08-25, directly prevents potential mismatches between the transaction shown to users and the one actually signed by the hardware wallet.
The patch aims to restore full user confidence in transaction validation on the Ethereum network.
The newly implemented safeguards in Ledger's Ethereum app version 1.22.2 specifically target the integrity of the transaction signing process. These technical changes ensure that the on-device display accurately reflects the data being cryptographically approved.
Prior to this update, a malicious actor could theoretically present a benign transaction on the screen while a different, harmful transaction was processed.
Public physical validation of this alleged substitution path remains limited to Flex, according to CryptoSlate. This highlights the ongoing challenge of verifying hardware wallet security mechanisms across all potential attack vectors. The patch is a proactive measure to secure user assets against sophisticated manipulation attempts.
