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.","state":0,"publishedAt":"2026-09-10T07:09:10.227+00:00","modifiedAt":"2026-10-13T21:40:40.196+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"skupper-router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Service Interconnect 2 for RHEL 8\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"skupper-router\",\n                    \"defaultStatus\": \"affected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0:3.5.3-1.el8\",\n                            \"lessThan\": \"*\",\n                            \"versionType\": \"rpm\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:/a:redhat:service_interconnect:2.0::el8\",\n                        \"cpe:/a:redhat:service_interconnect:2.0::el9\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"skupper-router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Service Interconnect 2 for RHEL 9\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"skupper-router\",\n                    \"defaultStatus\": \"affected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0:3.5.3-1.el9\",\n                            \"lessThan\": \"*\",\n                            \"versionType\": \"rpm\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:/a:redhat:service_interconnect:2.0::el8\",\n                        \"cpe:/a:redhat:service_interconnect:2.0::el9\"\n                    ]\n                }"},{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"service-interconnect/skupper-router-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Service Interconnect 2 for RHEL 9\",\n                    \"collectionURL\": \"https://catalog.redhat.com/software/containers/\",\n                    \"packageName\": \"service-interconnect/skupper-router-rhel9\",\n                    \"defaultStatus\": \"affected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"3.5.3-1\",\n                            \"lessThan\": \"*\",\n                            \"versionType\": \"rpm\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:/a:redhat:service_interconnect:2.0::el9\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://access.redhat.com/errata/RHSA-2026:82316","https://access.redhat.com/errata/RHSA-2026:82340","https://access.redhat.com/security/cve/CVE-2026-88763","https://bugzilla.redhat.com/show_bug.cgi?id=2531301"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88763","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88763","identifiers":["CVE-2026-88763"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
