CVE-2025-69893: A side-channel vulnerability exists in the implementation of BIP-39 mnemonic processing, as observed in Trezor One v1.13

A side-channel vulnerability (a security flaw where attackers extract secrets by analyzing physical signals like power consumption or timing) exists in how Trezor hardware wallets process BIP-39 mnemonics (seed phrases used to generate cryptocurrency keys) in versions 1.13.0 to 1.14.0. An attacker with physical access during wallet setup could use deep learning analysis to recover the mnemonic and steal assets, but the issue was patched.
