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...
