Ledger updates Ethereum application to version 1.22.2
A security update released on August 13 fixes a transaction substitution flaw in the Ethereum application for Ledger devices running version 1.22.1.
The vulnerability was identified by the Donjon team and stemmed from a race condition between display logic and the transaction buffer during APDU command processing.
▪️ Malicious smart contracts could manipulate confirmation details during signing.
▪️ OneKey researchers independently confirmed the exploit works only on outdated software.
▪️ Charles Guillemet noted that users with current firmware and patches remain fully protected.
This incident follows a separate security event when competitor Trezor reported a data leak affecting 13,689 users via logistics partner ShipMonk.
Timely patching prevents theoretical risks from becoming active threats.
