CVE-2025-22869 is a denial-of-service vulnerability in the Go SSH library's key-exchange handling that affects SSH servers implementing file-transfer protocols. A client that completes key exchange slowly or does not complete it can cause pending transfer content to be read into server memory without being transmitted. The resulting accumulation of buffered content can exhaust memory and disrupt the SSH service.
