CVE-2026-63410

The secp256k1-native Ruby library contains a vulnerability where native constant-time scalar multiplication via Point#mul or scalar_multiply_ct can leak secret scalar information through timing side-channels. This occurs because certain compiler toolchains, specifically GCC 14.3.0, 15.1.0, and 15...
