A Simple Transformer Pipeline for Full-Key Side-Channel Attacks on Uncropped Datasets

Deep learning-based side-channel analysis has historically focused on single-byte targets and manually cropped traces, which risks discarding exploitable leakage. While recent work has proposed specialized architectures and resampling techniques to address this gap, the literature lacks a simple...

Unity Linux 20.1070e Security Update: nss (UTSA-2026-030724)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-030724 advisory. The NSS code used for checking PKCS1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well...

Linux Distros Unpatched Vulnerability : CVE-2026-40203

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - When IMAP compression is enabled, the same compression state is reused across responses in a session, so response sizes depend on both attacker-supplied mail an...

CVE-2026-55785

free5GC is an open-source implementation of the 5G core network. Prior to 1.4.5, the AUSF component performs cryptographic authentication comparisons in internal/sbi/processor/ueauthentication.go with ordinary equality helpers. Auth5gAkaComfirmRequestProcedure compares RES and XRES with...

GHSA-FP46-6VFW-GC9C free5GC AUSF uses non-constant-time authentication comparisons and logs XRES* in 5G-AKA

Summary The AUSF component of free5GC compares authentication response values with normal Go equality helpers instead of constant-time cryptographic comparison functions. Two authentication flows are affected in internal/sbi/processor/ueauthentication.go: 1. 5G-AKA confirmation compares RES and...

Phalcon: Non-constant-time HMAC verification in `Encryption\Crypt::decrypt` (timing side-channel)

Summary Phalcon\Encryption\Crypt provides authenticated encryption: when useSigning is enabled the default, encrypt appends an HMAC tag and decrypt verifies it before returning the plaintext. The verification compares the attacker-supplied tag against the freshly computed HMAC using PHP/Zephir...

CVE-2026-42393

The comparison used for the doveadm password and API key is not fully timing safe and can reveal the length of the configured secret. An attacker with access to the same network as the doveadm service, able to make repeated requests and measure response timing accurately, can learn the length of...

ALPINE-CVE-2026-40203

When IMAP compression is enabled, the same compression state is reused across responses in a session, so response sizes depend on both attacker-supplied mail and other mail in the same mailbox. An attacker that can send mail to a user and can also observe the sizes of that user's IMAP traffic can...

CVE-2026-42393

CVE-2026-42393 affects the doveadm service in Open-Xchange's Dovecot implementation. The password and API key comparison is not fully timing-safe, allowing a network-adjacent attacker who can make repeated requests and accurately measure response times to learn the length of the configured secret...
