Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via the processGapMsg function. An attacker can cause excessive memory consumption and process termination by sending a specially crafted GAP packet with a large gap range, leading to an unbounded loop that inserts million...

CVE-2025-64438 Fast-DDS: Unbounded GAP range triggers OOM DoS under RELIABLE QoS

Fast DDS is a C++ implementation of the DDS Data Distribution Service standard of the OMG Object Management Group . Prior to versions 3.4.1, 3.3.1, and 2.6.11, a remotely triggerable Out-of-Memory OOM denial-of-service exists in Fast -DDS when processing RTPS GAP submessages under RELIABLE QoS. B...

CVE-2025-64438

Fast DDS (eProsima) before versions 3.4.1, 3.3.1, and 2.6.11 has a remotely triggerable OOM DoS via RTPS GAP submessages under RELIABLE QoS. A tiny GAP with a huge gap range causes StatefulReader::processGapMsg() to loop unboundedly, inserting millions of sequence numbers into WriterProxy::change...
