CVE-2025-62603 is an out-of-memory vulnerability affecting Fast DDS, a C++ implementation of the DDS standard, specifically versions prior to 3.4.1, 3.3.1, and 2.6.11. The flaw lies in how the ParticipantGenericMessage's message_data is parsed, where the entire DataHolderSeq is deserialized before validation, allowing an attacker to trigger an out-of-memory condition. This vulnerability has a CVSS score of 7.5 (High), indicating a network-based attack with low complexity that can lead to a complete denial of service (availability impact). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
