CVE-2026-22591: Fast DDS can be crashed by crafted filter message
CVE-2026-22591 · published 1 month ago
Summary
Versions of Fast DDS before 2.6.12, 2.14.6, 3.2.4 and 3.4.3 let a remote participant send a specially formed filter expression that consumes all stack space and stops the receiving program. This can cause a denial‑of‑service where legitimate data exchange stops. Upgrade to the listed patched versions or apply the vendor’s update to prevent the crash.

Original advisory text
Fast DDS DDSSQLFilter Recursive Parser Stack Exhaustion (Remote DoS)
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.
