CVE-2026-119277 - MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3
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, decoders for OK packet session-state blocks, column definition packets, text row data, or binary row data used server-declared lengths without confirming that the requested bytes remained in the receive buffer. The decoders could position reads, create sub-buffers, or decode strings beyond the packet boundary. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger unchecked ArrayIndexOutOfBoundsException or IllegalArgumentException failures inside JDBC calls and terminate connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.
