CVE-2026-119279 (GCVE-0-2026-119279)

Title

MariaDB Connector/J: Length-encoded integers larger than Integer.MAX_VALUE were truncated before being used as lengths

Summary

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.

GHSA-797X-P4MC-JWPM

Vulnerability from github – Published: 2026-10-30 23:00 – Updated: 2026-10-30 23:00

Summary

MariaDB Connector/J: Length-encoded integers larger than Integer.MAX_VALUE were truncated before being used as lengths

Details

Summary

MariaDB Connector/J narrowed 8-byte length-encoded integers received from the server to int without validation. A rogue or MitM server can send a value above Integer.MAX_VALUE whose truncation becomes a negative or arbitrary length.

Details

The protocol encodes lengths as length-encoded integers, whose 8-byte form the decoder (readLength() and readIntLengthEncodedNotNull()) returned as (int) readLong(). A value above Integer.MAX_VALUE therefore wrapped to a negative or unrelated int, used afterwards as a length to size allocations or reads, which ended in NegativeArraySizeException, out-of-bounds exceptions or oversized allocations.

The fix rejects any length-encoded value that does not fit a non-negative int with an explicit error.

Impact

Availability only: a malicious or compromised server, or a MitM, can crash the client's connection handling with unchecked exceptions or drive oversized allocations. Exploitation requires control of the server side of the connection; no authentication bypass, confidentiality or integrity impact.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
