{"id":"CVE-2026-32710","summary":"Heap-based Buffer Overflow in MariaDB","details":"MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSON_SCHEMA_VALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.","aliases":["BIT-mariadb-2026-32710","BIT-mariadb-min-2026-32710","BIT-mysql-client-2026-32710","GHSA-4rj5-2227-9wgc"],"modified":"2026-08-12T03:51:31.945069583Z","published":"2026-03-20T18:31:48.870Z","related":["SUSE-SU-2026:1367-1","SUSE-SU-2026:21407-1","openSUSE-SU-2026:10694-1","openSUSE-SU-2026:20629-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-122"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32710.json"},"references":[{"type":"WEB","url":"https://jira.mariadb.org/browse/MDEV-38356"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32710.json"},{"type":"ADVISORY","url":"https://github.com/MariaDB/server/security/advisories/GHSA-4rj5-2227-9wgc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32710"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mariadb/server","events":[{"introduced":"fa69b085b10f19a3a8b6e7adab27c104924333ae"},{"fixed":"054a893f1645b77e52a329a7fc8cf614eebd1fad"},{"introduced":"1c4aed7c680c0402d6e97e097f03815c0e9bf4c5"},{"fixed":"9bfea48ce1214cc4470f6f6f8a4e30352cef84e7"},{"introduced":"70117463f032d59f8e328335e19b59157d34cf07"},{"last_affected":"70117463f032d59f8e328335e19b59157d34cf07"}],"database_specific":{"source":["CPE_RANGE","CPE_STRING"],"cpe":["cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*","cpe:2.3:a:mariadb:mariadb:12.1.2:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"11.4.1"},{"fixed":"11.4.10"},{"introduced":"11.8.1"},{"fixed":"11.8.6"},{"introduced":"12.1.2"},{"last_affected":"12.1.2"}]}}],"versions":["12.1.2","mariadb-12.1.2","mariadb-11.8.4","mariadb-11.4.9","mariadb-11.8.3","mariadb-11.4.8","mariadb-11.8.2","mariadb-11.4.7","mariadb-11.4.6","mariadb-11.8.1","mariadb-11.4.5","mariadb-11.4.4","mariadb-11.4.3","mariadb-11.4.2","mariadb-11.4.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32710.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
