From 12.3.1 until 12.3.3 and 13.0.2, SYS_REFCURSOR handling is affected because cursor-array reallocation can leave stale references in routine contexts. A low-privileged attacker can open a large number of SYS_REFCURSORs and then fetch one to trigger a use-after-free that can enable remote code execution when combined with another vulnerability. This issue is fixed in versions 12.3.3 and 13.0.2.","evidence":"cve:CVE-2026-85748","products":[{"name":{"value":"server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"critical","structured":{"id":"CVE-2026-85748","aliases":["CVE-2026-85748"],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":9.9,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"MariaDB","product":"server","versions":[{"status":"affected","version":">= 12.3.1, < 12.3.3"},{"status":"affected","version":">= 13.0.1, < 13.0.2"}]}],"modified":"2026-10-16T16:54:40.841Z","provider":"cve","references":["https://github.com/MariaDB/server/security/advisories/GHSA-mv8g-9f7q-hprm","https://github.com/MariaDB/server/commit/91156c3de58762196605150ab3f756fe952592d1","https://github.com/MariaDB/server/commit/9b075b2cb53338f67e7230cc585e02d2d34514ed","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-40396","https://jira.mariadb.org/browse/MDEV-40639"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-85748","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-16T16:54:30.361781Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T16:54:40.841Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-10-16T16:28:55.829Z"}}},"related_cves":[{"value":"CVE-2026-85748","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":["publisher_severity"],"severity":"critical","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"critical"},"context_update":false}],"next_after":32758,"next_before":32758}
