CVE-2026-32322

Summary : The Soroban SDK (Rust) Fr scalar field types for BN254 and BLS12-381 were vulnerable prior to 22.0.11, 23.5.3, and 25.3.0 because equality comparisons used raw U256 values without reducing modulo the field modulus r. This could cause mathematically equal field elements to compare as une...

CVE-2024-1544

CVE-2024-1544 describes a bias in the ECDSA nonce generation when k is obtained as r mod n, where a control-flow dependent reduction leaks MSB bias in k. The issue can enable lattice-reduction based reconstruction of k for certain curves (e.g., SECP160R1 with about 15 bits of bias). The connected...
