CVE-2026-102824: Use of a Broken or Risky Cryptographic Algorithm

Russh is a Rust SSH client and server library. Prior to 0.63.0, the hybrid ML-KEM 768 and X25519 implementation in russh/src/kex/hybridmlkem.rs accepts an all-zero 32-byte peer X25519 public key in both serverdh and computesharedsecret, forcing the X25519 contribution to the combined shared secre...

RUSTSEC-2026-0330 Hybrid Encapsulation from Seed Panics on Short Seed

For a hybrid KEM public key of type PublicKey::WingKemDraft06 or PublicKey::X25519MlKem768Draft06, the PublicKey::encapsulatederand function would panic in an indexing operation on a seed input of length shorter than 32 bytes. Impact Applications encapsulating with an attacker controlled seed val...

A Drop-In KEM Replacement for Client Signatures in Post-Quantum SSH

The transition to post-quantum cryptography is reshaping the Secure Shell SSH protocol for remote administration. Post-quantum key exchange has been deployed in OpenSSH and is being standardized, while SSH authentication largely remains a signature-replacement effort. This path preserves the...

CVE-2026-74900

openssl_encrypt before version 1.4.0 has a flaw in pqc.py: when KEM decapsulation fails, it silently falls back to simulation mode, deriving a deterministic shared secret from just 16 bytes of the private key plus public encapsulated key data. An attacker with those 16 private-key bytes can compu...
