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.
Eprosima Fast DDS 是对象管理组（OMG）DDS（数据分发服务）标准的 C++ 实现。在版本 2.6.12、2.14.6、3.2.4 和 3.4.3 之前，Fast DDS 中基于 SQL 的内容过滤实现（DDSSQLFilter）存在一个安全缺陷：同一 DDS 域中的任意参与者，只需发送一条精心构造的 SEDP 子消息，其 中包含一个深度嵌套的过滤表达式，即可远程导致其他 Fast DDS 参与者崩溃。该问题已在版本 2.6.12、2.14.6、3.2.4 和 3.4.3 中修复。

Vulnerability Title
Fast DDS DDSSQLFilter Recursive Parser Stack Exhaustion (Remote DoS)
Source: CVE Program / CVE List V5
Vulnerability Description
eprosima Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). Prior to versions 2.6.12, 2.14.6, 3.2.4, and 3.4.3, Fast DDS’s implementation of SQL‑based content filtering (DDSSQLFilter) allows any participant in a DDS domain to remotely crash other Fast DDS participants by sending a single crafted SEDP `DATA` submessage whose `PID_CONTENT_FILTER_PROPERTY.filterExpression` contains a deeply nested filter expression. Versions 2.6.12, 2.14.6, 3.2.4, and 3.4.3 fix the issue.
