Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, `app_sms.c` copies externally controlled `SMS` lengths into `fixed in-struct buffers` without sufficient bounds checks, allowing an attacker to corrupt memory or crash Asterisk. The administrator must explicitly use the `SMS` dialplan application, which is useful when routing calls to or from `analog devices`, and must not have ensured that data passed to the application is valid. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.","state":0,"publishedAt":"2026-10-27T21:52:42.436+00:00","modifiedAt":"2026-10-27T21:52:42.436+00:00","affected":[{"ecosystem":"Vendor product","name":"asterisk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"asterisk\",\n                    \"product\": \"asterisk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 20.20.1\",\n                            \"status\": \"affected\"\n                        },\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\": \"< 20.7-cert11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 22.8-cert1-pre1, < 22.8-cert3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-q9fr-m7g8-6ph5","https://github.com/asterisk/asterisk/commit/15c66022dc441ec63d7bd5f53cf7f35db72964be","https://github.com/asterisk/asterisk/commit/38a2059eb77a91a6b6e76eeba5875c2b96027368","https://github.com/asterisk/asterisk/commit/59b74276f24ba104d859f3f05897c9b8d835a28a","https://github.com/asterisk/asterisk/commit/60f4ef3deac6b9af30519b46c13f103264038b82","https://github.com/asterisk/asterisk/commit/661d6a2fc5cc7744ab9d849ed3c73ae5066386df","https://github.com/asterisk/asterisk/commit/7048a3841df99e090b9d87246600373581629c98","https://github.com/asterisk/asterisk/commit/f46f63bd4d33665d336cf8b5998650b915222549","https://github.com/asterisk/asterisk/releases/tag/20.20.1","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-20.7-cert11","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-2026-57199","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57199","identifiers":["CVE-2026-57199"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
