CVE-2026-103224
Quick assessment
Affected
Eclipse Foundation Eclipse Vert.x
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Eclipse Vert.x 版本 [4.0.0, 4.5.34]、[5.0.0, 5.0.12]、[5.1.0, 5.1.9] 或 [5.2.0, 5.2.0] 中，MySQL 消息解码器会将传入的多包有效负载聚合到一个复合的直接内存缓冲区中，但没有任何累积大小限制。一个恶意的、已被攻陷的或处于中间人位置的 MySQL 服务器可以持续发送具有最大有效负载长度（0xFFFFFF）的数据包，从而阻止消息结束条件被触发，导致客户端无限制地分配直接内存，最终引发内存耗尽（Out-of-Memory）崩溃。该漏洞发生在

Vulnerability Description
In Eclipse Vert.x versions [4.0.0, 4.5.34] or [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], the MySQL message decoder aggregates inbound multi-packet payloads into a composite direct-memory buffer without any cumulative size limit. A malicious, compromised, or man-in-the-middle MySQL server can send a continuous stream of packets with the maximum payload length (0xFFFFFF), preventing the end-of-message condition from being reached, causing unbounded direct-memory allocation on the client and leading to an out-of-memory crash. This occurs before authentication completes.
The impacted component is io.vertx:vertx-mysql-client.
