{"id":"BIT-mariadb-min-2026-107815","summary":"MariaDB: one byte OOB write in DOS tables of the CONNECT engine","details":"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 CONNECT engine's DOS table type used an incorrect boundary check that permitted a one-byte null write beyond a stack buffer at an attacker-controlled offset. An authenticated user able to use the CONNECT engine could cause a crash and potentially remote code execution. 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.","aliases":["BIT-mariadb-2026-107815","BIT-mysql-client-2026-107815","CVE-2026-107815","GHSA-4wgx-ffg9-jrwq"],"modified":"2026-10-16T09:55:45.653462347Z","published":"2026-10-16T08:42:00.286Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/MariaDB/server/commit/b369925f6855d3e1f0ebcf453492724b99fda6f8"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3"},{"type":"ARTICLE","url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2"},{"type":"ADVISORY","url":"https://github.com/MariaDB/server/security/advisories/GHSA-4wgx-ffg9-jrwq"},{"type":"REPORT","url":"https://jira.mariadb.org/browse/MDEV-40637"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107815"}],"affected":[{"package":{"name":"mariadb-min","ecosystem":"Bitnami","purl":"pkg:bitnami/mariadb-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"10.6.1"},{"fixed":"10.6.28"},{"introduced":"10.11.1"},{"fixed":"10.11.19"},{"introduced":"11.4.1"},{"fixed":"11.4.13"},{"introduced":"11.8.1"},{"fixed":"11.8.9"},{"introduced":"12.3.1"},{"fixed":"12.3.3"},{"introduced":"13.0.1"},{"fixed":"13.0.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mariadb-min/BIT-mariadb-min-2026-107815.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
