{"id":"UBUNTU-CVE-2026-119276","details":"MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, when CLIENT_SESSION_TRACK was negotiated, the OkPacket.parse() and OkPacket.parseWithInfo() paths allocated byte arrays using server-declared lengths for the OK packet info field and session-state variable names and values before confirming that the bytes remained in the packet. A malicious or compromised server, or a machine-in-the-middle attacker, could send a small OK packet declaring a much larger length and repeatedly force attacker-controlled heap allocations before the subsequent copy failed. This could create garbage-collection pressure or an OutOfMemoryError in the client application. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.","modified":"2026-10-31T03:30:08.312649872Z","published":"2026-10-30T00:00:00Z","upstream":["CVE-2026-119276"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119276"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119276"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/b9e1ee8d9b4d820d70719504cdfd5c97f1aede5f"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/beb445fcf9294113878fc05ac77f0efdf0596ac6"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/ea8c7b6537e50053444188a9a3fd9cae99550f56"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.11"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-h599-m3w5-9m7x"}],"affected":[{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.0-1~18.04"],"ecosystem_specific":{"binaries":[{"binary_version":"2.3.0-1~18.04","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.2-1build2","2.5.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.5.3-1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.2-1","2.7.4-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.7.4-1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1","2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119276.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
