The vulnerability in Trezor's TROPIC01 Secure Element chip was uncovered by an audit carried out by the Ledger Donjon team.

The flaw affects only one of the wallet's multiple security layers and would require physical access, specialized equipment and advanced expertise to exploit.

Trezor and Tropic Square disclosed a TROPIC01 secure element flaw found by Ledger Donjon but said Safe 7 user funds are not at risk.
