CVE-2026-73430

Russh is a Rust SSH client & server library. Prior to 0.62.4, an unauthenticated SSH client can cause a denial of service by sending SSHMSGKEXECDHINIT with a 32-byte all-zero QC value. Curve25519Kex::serverdh in russh/src/kex/curve25519.rs accepts the all-zero peer public value and computes an...

Russh: Pre-auth remote panic via all-zero Curve25519 peer public value (encode_mpint OOB)

A pre-authentication denial-of-service panic in russh 0.62.2 commit c4be19f1915c8682f4615c3fd50008512b474491, current default branch main as of 2026-07-22. An unauthenticated client sends a single SSHMSGKEXECDHINIT whose QC is 32 zero bytes. russh's Curve25519 KEX does not reject the all-zero pee...

CVE-2026-44434

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit dccf5d4, Quicly was vulnerable to stateless reset injection through lack of packet entry validation. The QUIC protocol is designed to withstand packet injection attacks, once the...

CVE-2026-41207 netty-incubator-codec-ohttp's HPKEContext operations may produce empty byte[] on failures

The netty incubator codec.bhttp is a java language binary http parser. Prior to version 0.0.21.Final, HKDFexpand returns non-NULL on failure. The byte is filled with zeros and has no way to distinguish success from failure. Since this output is used as HKDF key material for the response AEAD, a...

netty-incubator-codec-ohttp 安全特征问题漏洞

netty-incubator-codec-ohttp is an application developed by the Netty community. Versions prior to 0.0.21.Final of netty-incubator-codec-ohttp contain a security vulnerability. This vulnerability arises from returning a non-empty value when HKDF-expand fails, which may lead to the use of a key wit...

GHSA-434V-X5QV-PMH6 libcrux has All-Zero Key Generation Upon Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...

RUSTSEC-2026-0072 Missing Check for All-Zero X25519 Shared Secret

Computing an X25519 shared secret with x25519dalek::StaticSecret::diffiehellman does not include the check that the key exchange was contributory, i.e. does not ensure on its own that the resulting shared secret is non-zero. Impact RFC 9180 mandates that implementations of HPKE must check for all...
