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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:82316** · Red Hat · fixed in: Red Hat Service Interconnect 2 for RHEL 8, Red Hat Service Interconnect 2 · released 2026-10-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:82316)\n- **RHSA-2026:82340** · Red Hat · fixed in: Red Hat Service Interconnect 2 · released 2026-10-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:82340)","depth":"sunlit","depthScore":33,"depthScoreParts":{"impact":32.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
