Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an unbounded `memcpy` of `OGG/Speex` packet data in `format_ogg_speex` can cause a heap buffer overflow and crash Asterisk when reading a file containing corrupted Speex audio. The attacker must create the file and make it available to Asterisk either through sufficiently elevated privileges or by convincing an Asterisk administrator to make it available. Asterisk must also be configured to play that file. 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":"2026-10-27T16:35:59.337+00:00","modifiedAt":"2026-10-27T16:35:59.337+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:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7,"severity":"HIGH"}],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-8jhw-m2hg-vp3h","https://github.com/asterisk/asterisk/commit/0a2c1d9e910f7c4dfffa05e328accb8a96990df8","https://github.com/asterisk/asterisk/commit/0e6d761ed83f1671632c91805252767eae85e1a2","https://github.com/asterisk/asterisk/commit/1cf189549994e0898954c814ce5a023cd969f1db","https://github.com/asterisk/asterisk/commit/29026ece6fdd1834bb8f49c013ef163745ff2bbd","https://github.com/asterisk/asterisk/commit/336ebe762bf6dfaf279796700de8ab51f7acd2f3","https://github.com/asterisk/asterisk/commit/ccec146953b5e13043a36663af84e5a50ca633a6","https://github.com/asterisk/asterisk/commit/dbcf38933866f0ddd023bc1814a78d4c750b0809","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-2026-57197","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57197","identifiers":["CVE-2026-57197"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
