{"id":"BIT-mysql-client-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","CVE-2026-32710","GHSA-4rj5-2227-9wgc"],"modified":"2026-04-01T09:15:15.261620Z","published":"2026-03-25T08:49:03.929Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/MariaDB/server/security/advisories/GHSA-4rj5-2227-9wgc"},{"type":"WEB","url":"https://jira.mariadb.org/browse/MDEV-38356"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32710"}],"affected":[{"package":{"name":"mysql-client","ecosystem":"Bitnami","purl":"pkg:bitnami/mysql-client"},"ranges":[{"type":"SEMVER","events":[{"introduced":"11.4.1"},{"fixed":"11.4.10"},{"introduced":"11.8.1"},{"fixed":"11.8.6"},{"introduced":"12.1.2"},{"fixed":"12.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mysql-client/BIT-mysql-client-2026-32710.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}],"schema_version":"1.7.5"}
