Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a group does not have...

Issue summary: A timing side-channel which could potentially allow remote recovery of the private key exists in the SM2 algorithm implementation on 64 bit ARM platforms. Impact summary: A timing side-channel in SM2 signature computations on 64 bit ARM platforms could allow recovering the private...

Machine-Checked Cardinality Bounds for Masked Barrett Reduction: A 1-Bit Side-Channel Leakage Barrier in Post-Quantum Cryptographic Hardware

Barrett reduction is the nonlinear core of every practical NTT-based post-quantum cryptography implementation. Existing composition frameworks ISW, t-SNI, PINI, DOM address Boolean masking over GF2; none provides a machine-checked characterization of Barrett's leakage under first-order arithmetic...

GHSA-6X2Q-H3CR-8J2H Traefik: A timing side-channel vulnerability allows for valid username enumeration via BasicAuth middleware

Summary There is a timing side-channel vulnerability in Traefik's BasicAuth middleware that allows an attacker to enumerate valid usernames through response-time differences. The variable intended to hold a constant-time fallback secret always resolves to an empty string, causing the constant-tim...

CVE-2026-41418

4ga Boards prior to 3.3.5 is vulnerable to user enumeration via a timing side-channel on POST /api/access-tokens. Valid username/email with wrong password yields ~74 ms bcrypt.compareSync(), vs ~17 ms for invalid username/email, creating a ~4.4× timing difference. Root cause: timing variance in l...
