The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the...

Non-constant time Authentication Tag Check in AES-GCM Decryption

AES-GCM decryption used an implementation for checking the provided authentication tag against the recomputed authentication tag that was intended to be constant-time, but resulted in non-constant-time code generation in certain circumstances. Note that libcrux-aesgcm does not give guarantees on...

wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine executes in variable time based on operand values. This affects multiple SP math functions sp 256 mul 9, sp 256 sqr 9, etc., leading to a...

In wolfSSL 5.8.4, constant-time masking logic in sp 256 get entry 256 9 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover...

pyquorum: Timing side‑channel in mul_mod

ImpactThe mulmod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand the exponent. An attacker who can measure the time of secret‑sharing operations e.g., via a remote service could progressively recover the value...

Anticipating Decoder Side-Channel Attacks in Fault-Tolerant Quantum Computers

As quantum computing emerges as an applied technology, there is a growing need to protect quantum computers against information security attacks. This work identifies a new class of side-channel attacks against fault-tolerant quantum computers, in which the syndrome data that is sent to the decod...

ARMOR-IMC: Adaptive Resource Mapping for Operational Robustness Via Secure In-Memory Computing

The massive data-movement overhead in traditional architectures has led to the adoption of In-Memory Computing IMC for energy-efficient Deep Neural Network DNN processing. By leveraging emerging devices like Spin-Orbit Torque Magnetic Tunnel Junctions SOT-MTJs, IMC bypasses the "memory wall" and...

CVE-2026-12426 Members <= 3.2.22 - Unauthenticated Sensitive Information Disclosure via REST API Pagination Side Channel

The Members – Membership & User Role Editor Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.22 via the membersfilterprotectedpostsforrest. This makes it possible for unauthenticated attackers to extract determine the existence...

CVE-2026-54736 Phalcon: Non-constant-time HMAC verification in `Encryption\Crypt::decrypt` (timing side-channel)

Phalcon is a high-performance, full-stack PHP framework. Prior to 5.14.1, Phalcon\Encryption\Crypt::decrypt compares the attacker-supplied HMAC tag against the freshly computed HMAC using PHP/Zephir identity comparison, which lowers to a byte-wise comparison that returns early on the first...

PT-2026-57320

Name of the Vulnerable Software and Affected Versions Phalcon versions prior to 5.14.1 Description The decrypt function within PhalconEncryptionCrypt uses a byte-wise identity comparison to verify the HMAC tag. Because this comparison returns early upon encountering the first differing byte, it...

UBUNTU-CVE-2026-15041

A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash...

PT-2026-61005

Name of the Vulnerable Software and Affected Versions xrdp versions prior to 0.10.6.1 Description The login interface contains a timing side-channel issue. A remote attacker can exploit discrepancies in response processing times to determine if a specific username exists on the system, resulting ...
