CVE-2026-103415 is a critical out-of-bounds write vulnerability in the Eclipse Foundation NetX Duo TLS 1.3 client. It occurs when processing a HelloRetryRequest, where the client copies a server-provided cookie into its second ClientHello message without verifying the cookie fits in the packet buffer. This allows a malicious or compromised server to overwrite memory beyond the allocated buffer before certificate authentication completes. Only the client-side TLS path is affected.
