CVE-2026-88763: Red Hat Service Interconnect 2

Medium severity, CVSS 5.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
