CVE-2026-73429

CVE-2026-73429 affects Russh (Rust SSH client/server library) prior to v0.62.4. A malicious SSH server can trigger a deterministic panic in the client during KEX_ECDH_REPLY handling when the server_ephemeral value is not 32 bytes, as Curve25519Kex::compute_shared_secret passes the decoded value t...

Russh: client wrong-length X25519 `clone_from_slice` panic (pre-auth DoS)

Summary A malicious SSH server can crash a russh client session with a single malformed key-exchange reply, causing a pre-authentication Denial-of-Service before the server host key is verified. The embedding process itself stays up, but the connection is killed deterministically. Details Every...
