patch available.

  - 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. (CVE-2026-119279)

Note that Nessus relies on the presence of the package as reported by the vendor.");
