CVE-2026-5419 Gnutls: gnutls: information disclosure via timing side-channel in pkcs#7 padding removal

A flaw was found in gnutls. The PKCS7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of...

CVE-2026-5419

The CVE-2026-5419 issue affects the GnuTLS library: PKCS#7 padding removal during decryption may leak padding information via timing differences due to non-constant-time checks. This is an information-disclosure risk. Reports and patches across multiple distros exist: SUSE-2026-2115; Ubuntu USN-8...

GnuTLS 信息泄露漏洞

GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. There is a security vulnerability in gnutls, which stems from the fact that the PKCS7 padding check does not occur at a constant time during decryptio...

Improving IoT Intrusion Detection through SMOTE-Based Oversampling and Extended Multi-Model Evaluation on Side-Channel Power Data

The detection of intrusions in IoT-based networks poses challenges that cannot be overcome using traditional machine learning methods. Perhaps the biggest of them is related to the presence of a class imbalance in the side-channel dataset, where the number of samples in the normal class compared ...

CLSA-2026-1779697425 postgresql: Fix of CVE-2026-6478

CVE-2026-6478: backport upstream prerequisite that introduces the timingsafebcmp constant-time memory comparison helper, then apply it to SCRAM and MD5 authentication paths that previously used memcmp or strcmp on password hashes, computed keys, and SCRAM nonces, to prevent timing-side-channel...

Pre-Characterization of Electromagnetic Side-Channel Leakage Using Publicly Available Information: A Case Study on E-Voting Interfaces

In this work, we study the interface of the Brazilian e-Voting Machine BVM in the context of electromagnetic side-channel threats commonly referred to as TEMPEST attacks. In a TEMPEST attack against video displays, an eavesdropper uses Software-Defined Radios SDRs to recover sensitive information...
