{"id":"CVE-2026-107816","published":"2026-10-09T18:17:03.060","lastModified":"2026-10-14T14:12:42.630","description":"MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the qc_info plugin could be confused by a query containing embedded null bytes. Reading information_schema.query_cache_info after such a query was cached could access data beyond the end of a heap-allocated buffer, potentially disclosing adjacent memory or crashing the server. 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.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:L","cwes":["CWE-125"],"vendors":["mariadb"],"products":["mariadb"],"references":[{"url":"https://github.com/MariaDB/server/commit/0931994096b84ecc9ffc8eb3517c7e09e6e8631e","tags":["Patch"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-wfqg-88r5-55f6","tags":["Vendor Advisory"]},{"url":"https://jira.mariadb.org/browse/MDEV-40670","tags":["Issue Tracking"]}],"exploitRefs":[{"url":"https://github.com/MariaDB/server/commit/0931994096b84ecc9ffc8eb3517c7e09e6e8631e","tags":["Patch"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-wfqg-88r5-55f6","tags":["Vendor Advisory"]}],"hasPoc":true,"ai":null}
