CVE-2026-18036 NTRU leaks private key information by reducing secret values with a non-constant-time integer division

In Bouncy Castle for Java before 1.86, NTRU reduced secret values with the % operator in three helpers whose reference implementations are deliberately division-free, so each reduction was carried out by an integer division whose latency depends on the secret operand. Polynomial.modQ divided by a...

NCC Group: FIPS 203 基于模块格的密钥封装机制标准 FIPS 203（初始公开草案）基于模块格的密钥封装机制标准，使用纯 Rust 编写，适用于服务器、桌面、浏览器和嵌入式应用。源仓库包含演示基准测试、嵌入式目标、恒定时间统计测量、模糊测试、WASM 执行、C FFI 和 Python 绑定的示例。 这个 crate 以纯 Rust 实现了 FIPS 203 草案 标准，依赖项最少且为主流，并且不包含任何 unsafe 代码 。所有三组安全参数集均得到完整支持并经过测试。该实现以恒定时间运行（rho 除外，rho...

openssl: openssl: information disclosure via non-constant-time SM2 scalar multiplication on ARM64 and RISC-V

A flaw was found in OpenSSL. The optimized scalar point multiplication used for SM2 cryptographic operations on ARM64 and RISC-V architectures does not execute in constant time. An attacker capable of measuring execution times or observing processor cache-access patterns can exploit this side...
