CVE-2026-22992

Mode C: The CVE-2026-22992 issue affects the Linux kernel’s libceph stack. Root cause: mon_handle_auth_done() no longer propagates errors from ceph_auth_handle_reply_done(), so a failure during authentication could be misinterpreted by higher layers while msgr2 proceeds with session setup. Potent...
