CVE-2026-22591

Fast DDS DDSSQLFilter Recursive Parser Stack Exhaustion (Remote DoS)

7.5 High

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.
