CVE-2026-35387

OpenSSH before 10.3 is affected by CVE-2026-35387: when listing any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms, the client/server may misinterpret this as enabling all ECDSA algorithms. The result is the unintended use of ECDSA keys, with confidentiality impact lis...

CVE-2026-35387

OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms...

Quantum-Safe Code Auditing: LLM-Assisted Static Analysis and Quantum-Aware Risk Scoring for Post-Quantum Cryptography Migration

The impending arrival of cryptographically relevant quantum computers CRQCs threatens the security foundations of modern software: Shor's algorithm breaks RSA, ECDSA, ECDH, and Diffie-Hellman, while Grover's algorithm reduces the effective security of symmetric and hash-based schemes. Despite NIS...
