CVE-2026-3497 affects distribution-added GSSAPI key exchange patches for OpenSSH, not upstream OpenSSH itself. An unexpected GSSAPI message type during server-side key exchange triggers an error path that calls sshpkt_disconnect(), which does not terminate the process. Execution consequently continues without initializing relevant connection pointers to NULL, and subsequent accesses can reference arbitrary memory. This undefined behavior can cause denial of service or information disclosure, with consequences heavily dependent on compiler hardening. Debian also identifies potential arbitrary code execution.
