[OE-core][Scarthgap][PATCH] openssh: set status for CVE-2026-3497

[Sudhir Dumbhare -X (sudumbha - E INFOCHIPS PRIVATE LIMITED at Cisco)]

From: Sudhir Dumbhare <sudumbha@cisco.com>

Analysis:
 - CVE-2026-3497 affects downstream OpenSSH GSSAPI Key Exchange patches.
 - The vulnerable code uses sshpkt_disconnect() in the GSSAPI KEX server path.
 - Upstream OpenSSH/OE-Core does not carry the vulnerable GSSAPI key-exchange delta.
 - Hence ignoring the CVE for this version.

Hello,

That looks like this is needed on wrynose and master as well.

Can you send this to those branches and ping back here?

Thanks!
