From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, ST_Area reads beyond the allocated buffer when processing invalid WKB for a MultiPolygon because the multi-polygon parser advances past a nested geometry header without first verifying enough input remains. A low-privileged remote attacker can supply malformed spatial data to disclose memory useful for bypassing ASLR as part of a multi-vulnerability chain. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.","state":0,"publishedAt":"2026-10-16T16:30:30.866+00:00","modifiedAt":"2026-10-19T12:39:16.848+00:00","affected":[{"ecosystem":"Vendor product","name":"server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MariaDB\",\n                    \"product\": \"server\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 10.6.1, < 10.6.28\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 10.11.1, < 10.11.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.4.1, < 11.4.13\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.8.1, < 11.8.9\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 12.3.1, < 12.3.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 13.0.1, < 13.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/MariaDB/server/security/advisories/GHSA-p7v9-24h4-mch8","https://github.com/MariaDB/server/commit/2bf355e361db85153fdfba7b8a0f0d114d6a26ce","https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","https://jira.mariadb.org/browse/MDEV-40328"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85745","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85745","identifiers":["CVE-2026-85745"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
