CVE-2026-92542 | BDVDB-2026-384205 Detail
DockerDocker Engine
Description#
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
Impact#
An unprivileged user on a Swarm node can trivially inject forged Ethernet frames into an encrypted overlay network on another node.
