IKE state is retained in memory after the client closes the connection, storing a pointer to iface_endpoint inside ike_sa.sa-\u003est_iface_endpoint. Once this invalid pointer is used, the daemon crashes and restarts. This vulnerability can be triggered before the remote peer has authenticated itself. Continued exploitation can lead to a denial of service. Remote code execution could be possible. The IKE over TCP option is not enabled by default; only configurations that contain listen-tcp=yes are affected.","status":"published","published":"2026-10-13T22:19:30Z","modified":"2026-11-05T05:40:51Z","updated_at":"2026-11-05T16:41:18.199293Z"}]}}
