CVE-2026-92542 (GCVE-0-2026-92542)

Vulnerability from cvelistv5 – Published: 2026-10-07 16:42 – Updated: 2026-10-07 20:30
VLAI
Title
Blind VXLAN injection into encrypted overlay networks from cluster peer
Summary
The firewall rules which mark VXLAN datagrams for encryption indiscriminately match both authentic VXLAN datagrams sent from the kernel and forged datagrams sent by user processes. Any packet sent from the host network namespace of a Linux Swarm node is encrypted with the overlay-network IPsec parameters which meets the following criteria: - UDP datagram - Destination port is the Swarm data-path port - Datagram starts with a VXLAN header for the VNI of an encrypted overlay network which any running container on the node is connected to
