From 21.0.0-pre1 until Asterisk 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 22.8-cert3, the `chan_ooh323` `Q.931 party-number parser` lacks the `CVE-2022-37325` fix because that fix was never forward-ported from Asterisk 20 to later versions. Malformed Q.931 elements in an `OOH323 request` can therefore crash Asterisk. This issue affects Asterisk versions greater than 20. The `chan_ooh323` addon channel driver must be explicitly compiled and installed, which is not the default, and its port must be publicly reachable. This issue is fixed in Asterisk 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 22.8-cert3.","state":0,"publishedAt":"2026-10-27T21:21:55.833+00:00","modifiedAt":"2026-10-28T16:13:12.086+00:00","affected":[{"ecosystem":"Vendor product","name":"asterisk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"asterisk\",\n                    \"product\": \"asterisk\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 21.0.0-pre1, < 21.12.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 22.0.0-pre1, < 22.10.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 23.0.0-pre1, < 23.4.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"certified-asterisk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"asterisk\",\n                    \"product\": \"certified-asterisk\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 22.8-cert1-pre1, < 22.8-cert3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-h5hv-jmgj-92q2","https://github.com/asterisk/asterisk/commit/07b9740cbc371ffa7936cf368089fd073250ea7c","https://github.com/asterisk/asterisk/commit/0e776a837106d5d0d14503a53388337931045164","https://github.com/asterisk/asterisk/commit/42d3552d2ac0efbb68c9ec7ade898b6de0bfa033","https://github.com/asterisk/asterisk/commit/46c6c652d1de9bfbb061fab0b1f681cf60660998","https://github.com/asterisk/asterisk/commit/62a7a7037b1a145cabf95895b119cbae4d3c5a4f","https://github.com/asterisk/asterisk/releases/tag/21.12.3","https://github.com/asterisk/asterisk/releases/tag/22.10.1","https://github.com/asterisk/asterisk/releases/tag/23.4.1","https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","https://github.com/asterisk/asterisk/tree/24.0.0-pre1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57186","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57186","identifiers":["CVE-2026-57186"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
