CVE-2026-46598 is an input-validation vulnerability in the Go cryptography module's SSH agent client. Certain crafted wire-format inputs are cast into an invalid ed25519.PrivateKey without adequate validation. Subsequent use of the malformed key triggers a panic, potentially crashing the affected client application and causing denial of service.
