Router crash via unbounded AMQP field recursion
Published Sep 10, 2026 · Updated Sep 10, 2026
Denial of service in Red Hat Service Interconnect allows remote authenticated users to crash skupper-router with a crafted AMQP message. The AMQP field parser recursively processes nested fields without a depth bound, exhausting stack memory and terminating the router process. A valid X.509 certificate signed by the interconnect network certificate authority is required; the crash drops active connections and prevents new traffic through the affected node.
