Red Hat Service Interconnect 2: denial of service
Medium5.9CVE-2026-88763 · Published Sep 10, 2026 · updated Sep 14, 2026
A flaw was found in the skupper-router component of Red Hat Service Interconnect, which is used to provide secure communication between distributed services. The issue occurs when the router processes a specially crafted network message using its AMQP field parser. Due to a lack of bounds on recursion during parsing, the router can run out of stack memory and crash, leading to a denial of service for the interconnected network.
