{"id":"CVE-2022-23606","summary":"Crash when a cluster is deleted in Envoy","details":"Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade.","aliases":["BIT-envoy-2022-23606","GHSA-9vp2-4cp7-vvxf"],"modified":"2026-05-18T05:53:19.835761839Z","published":"2022-02-22T22:20:13Z","database_specific":{"cwe_ids":["CWE-674"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23606.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23606.json"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-9vp2-4cp7-vvxf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23606"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/4b6dd3b53cd5c6d4d4df378a2fc62c1707522b31"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/envoyproxy/envoy","events":[{"introduced":"a9d72603c68da3a10a1c0d021d01c7877e6f2a30"},{"fixed":"af50070ee60866874b0a9383daf9364e884ded22"}]}],"versions":["v1.21.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-23606.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H"}]}
