CVE-2026-3503
Protection mechanism failure in wolfCrypt post-quantum implementations ML-KEM and ML-DSA in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during...
Use of a Broken or Risky Cryptographic Algorithm
Overview Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm in the OpenID Connect authentication. An attacker can impersonate any user and obtain unauthorized S3 credentials with any policy, including administrative privileges, by forging identity...
CVE-2026-0819 Stack buffer overflow in PKCS7 SignedData encoding with custom signed attributes
A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality. In wcPKCS7BuildSignedAttributes, when adding custom signed attributes, the code passes an incorrect capacity value esd-signedAttribsCount to EncodeAttributes instead of the remaining available space...
RUSTSEC-2026-0042 CRL Distribution Point Scope Check Logic Error in AWS-LC
A logic error in CRL distribution point matching in AWS-LC allows a revoked certificate to bypass revocation checks during certificate validation, when the application enables CRL checking and uses partitioned CRLs with Issuing Distribution Point IDP extensions. Customers of AWS services do not...
PT-2026-26369
Summary AWS-LC is an open-source, general-purpose cryptographic library. Impact A logic error in CRL distribution point matching in AWS-LC allows a revoked certificate to bypass revocation checks during certificate validation, when the application enables CRL checking and uses partitioned CRLs wi...
Benchmarking Post-Quantum Cryptography on Resource-Constrained IoT Devices: ML-KEM and ML-DSA on ARM Cortex-M0+
The migration to post-quantum cryptography is urgent for Internet of Things devices with 10-20 year lifespans, yet no systematic benchmarks exist for the finalised NIST standards on the most constrained 32-bit processor class. This paper presents the first isolated algorithm-level benchmarks of...
A New Approach to Code Smoothing Bounds
To analyze the security of code-based cryptosystems, the smoothing parameter, which is closely related to the total variation distance of codes, has been investigated. While previous studies have bounded this distance using the Fourier transform on locally compact abelian groups, we take an...
openssl: OpenSSL: Arbitrary code execution due to out-of-bounds write in PKCS#12 processing
A flaw was found in OpenSSL. When processing a specially crafted PKCS12 Personal Information Exchange Syntax Standard file, a remote attacker can exploit an out-of-bounds write vulnerability. This issue, occurring within the OPENSSLuni2utf8 function, leads to memory corruption by writing data...
CVE-2026-4258
Affected software: sjcl (Stanford Javascript Crypto Library). Vulnerability: Improper verification of cryptographic signatures due to missing point-on-curve validation in sjcl.ecc.basicKey.publicKey(). This allows an attacker to recover a victim’s ECDH private key by sending crafted off-curve pub...
SUSE CVE-2026-28490
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.9, a cryptographic padding oracle vulnerability was identified in the Authlib Python library concerning the implementation of the JSON Web Encryption JWE RSA15 key management algorithm. Authlib registe...
Synchronized DNA Sources for Unconditionally Secure Cryptography
Secure communication is the cornerstone of modern infrastructures, yet achieving unconditional security -resistant to any computational attack- remains a fundamental challenge. The One-Time Pad OTP, proven by Shannon to offer perfect secrecy, requires a shared random key as long as the message,...
