CVE-2025-69893

CVE-2025-69893 describes a side-channel vulnerability in BIP-39 mnemonic processing observed in Trezor hardware wallets (One v1.13.0–v1.14.0, T v1.13.0–v1.14.0, Safe v1.13.0–v1.14.0). The root cause is non-constant time execution and specific branch patterns during word search dictated by the BIP...

Design/Logic Flaw

BIP-143 in the Bitcoin protocol specification mishandles the signing of a Segwit transaction, which allows attackers to trick a user into making two signatures in certain cases, potentially leading to a huge transaction fee. NOTE: this affects all hardware wallets. It was fixed in 1.9.1 for the...
