{"id":"UBUNTU-CVE-2026-119279","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 3.5.10, the ReadableByteBuf.readLength() and ReadableByteBuf.readIntLengthEncodedNotNull() methods narrowed the protocol's unsigned 8-byte length-encoded integer to a Java int without checking that the value fit a non-negative integer. Values above Integer.MAX_VALUE could wrap to a negative or unrelated length that downstream allocation and read paths used. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger NegativeArraySizeException, out-of-bounds failures, or oversized allocation behavior in client connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.10.","modified":"2026-10-31T03:30:03.261313258Z","published":"2026-10-30T00:00:00Z","upstream":["CVE-2026-119279"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119279"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119279"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/30d4a883377a9b7762e02ee2c60d54567032ab99"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/bfd9f5ad666a6f7f5401a5b78f2ac2fbd6df8667"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/dbbadc3e215c47bdb913ddf50739ada09a7f23ea"},{"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/3.5.10"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-797x-p4mc-jwpm"}],"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_name":"libmariadb-java","binary_version":"2.3.0-1~18.04"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119279.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_name":"libmariadb-java","binary_version":"2.5.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119279.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_name":"libmariadb-java","binary_version":"2.7.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119279.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-2026-119279.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_version":"2.7.6-1build1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119279.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-2026-119279.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"}]}
