CVE-2026-46597 is an integer-underflow denial-of-service vulnerability in the AES-GCM packet decoder of golang.org/x/crypto/ssh. An incorrectly positioned conversion from bytes to an integer permits byte arithmetic to underflow when processing a specially crafted SSH AES-GCM packet. The resulting invalid length calculation causes the server-side SSH implementation to panic.
