From: Devansh Patel <[email protected]> Analysis: - CVE-2026-59998 concerns an undocumented limitation of GSSAPIStrictAcceptorCheck in Windows Active Directory environments [1]. - Upstream OpenSSH 10.4 only documents the existing behavior and provides no code remediation [2]. - The recipe disables Kerberos/GSSAPI by default. Mark the CVE not-applicable-config when PACKAGECONFIG lacks kerberos, and unpatched when kerberos is enabled.
