Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length

The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...

CVE-2026-3849

CVE-2026-3849 describes a stack buffer overflow in wolfSSL 5.8.4’s ECH (Encrypted Client Hello) support, specifically in wc_HpkeLabeledExtract triggered by an oversized ECH config. The issue could allow remote execution or a client crash when a malicious TLS server sends a crafted ECH config. ECH...

PT-2026-26349

Name of the Vulnerable Software and Affected Versions wolfSSL version 5.8.4 Description A flaw exists in wolfSSL 5.8.4’s Encrypted Client Hello ECH support. A specially crafted ECH configuration from a malicious TLS server can trigger a stack buffer overflow on the client side. This could...

Nonce Reuse in HPKE Context

The sequence number that is used to compute the AEAD nonce when using a re-usable HPKE context is incremented after each seal or open operation. This sequence number was stored as a u32 and used regular addition on u32 for the increment, meaning in release mode it would silently wrap around to 0...

On the Impossibility of Simulation Security for Quantum Functional Encryption

Functional encryption is a powerful cryptographic primitive that enables fine-grained access to encrypted data and underlies numerous applications. Although the ideal security notion for FE simulation security has been shown to be impossible in the classical setting, those impossibility results...

MiracleLinux 7 : java-1.8.0-openjdk-1.8.0.151-1.b12.el7 (AXSA:2017-2339:07)

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-2339:07 advisory. Multiple flaws were discovered in the RMI and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to...

RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE

Summary A denial-of-service vulnerability exists in the SM2 public-key encryption PKE implementation: the decrypt path performs unchecked slice::splitat operations on input buffers derived from untrusted ciphertext. An attacker can submit short/undersized ciphertext or carefully-crafted DER-encod...

Jervis 加密问题漏洞

Jervis is an automation tool from the personal developer Sam Gleske. A vulnerability in cryptographic issues exists in versions prior to Jervis 2.2, which stems from the use of PKCS1Encoding encryption that is vulnerable to the Bleichenbacher padding prediction attack...

CVE-2026-22700 RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE

RustCrypto: Elliptic Curves is general purpose Elliptic Curve Cryptography ECC support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof. In versions 0.14.0-pre.0 and 0.14.0-rc.0, a denial-of-service vulnerability...

CVE-2026-22698 RustCrypto SM2-PKE has 32-bit Biased Nonce Vulnerability

RustCrypto: Elliptic Curves is general purpose Elliptic Curve Cryptography ECC support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof. In versions 0.14.0-pre.0 and 0.14.0-rc.0, a critical vulnerability exists in...

CVE-2026-22698

CVE-2026-22698 affects the RustCrypto Elliptic Curves library (SM2 PKE) in versions 0.14.0-pre.0 through 0.14.0-rc.0. The root cause is a unit-mismatch in the nonce generation path: the code computes the nonce length as a 32-bit value but feeds it as a bit-length to the RNG, producing a 32-bit en...

SM2-PKE has 32-bit Biased Nonce Vulnerability

Summary A critical vulnerability exists in the SM2 Public Key Encryption PKE implementation where the ephemeral nonce k is generated with severely reduced entropy. A unit mismatch error causes the nonce generation function to request only 32 bits of randomness instead of the expected 256 bits. Th...
