CVE-2026-77696

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn information about the per-signature secret nonce, which over many signatures can, via a lattice / Hidd...

CVE-2026-77696

OpenSSL is affected by a timing side-channel vulnerability during SM2 signature generation . The issue stems from the use of variable-time BIGNUM operations on secret values, specifically the secret nonce and the private key. An attacker capable of measuring the time taken to produce these signat...

CVE-2026-54872 Timing Side-Channel in Scalar Multiplication for Non-NIST EC Curves

Issue summary: The generic elliptic-curve scalar multiplication used for ECDSA and SM2 signature operations with curves that do not have a dedicated implementation leaks information about the secret nonce through timing. Impact summary: An attacker able to measure signing times may learn...

CVE-2026-70405

CVE-2026-70405 is an improper input validation vulnerability in the Erlang/OTP snmp module. The function snmp_pdus:dec_integer_notag/1 defaults its size limit to infinity, causing do_dec_integer_notag/2 to accumulate a BER INTEGER value via recursive shift-and-or operations whose cost grows super...

Relational Hoare Logic for Realistically Modelled Machine Code

Many security- and performance-critical domains, such as cryptography, rely on low-level verification to minimize the trusted computing surface and allow code to be written directly in assembly. However, verifying assembly code against a realistic machine model is a challenging task. Furthermore,...
