CVE-2025-64098
No affected components available
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, when the security mode is enabled, modifying the DATA Submessage within an
SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t
he fields of PID_IDENTITY_TOKEN or PID_PERMISSIONS_TOKEN in the DATA Submessage are tampered with — specifically by ta
mpering with the the vecsize value read by readOctetVector — a 32-bit integer overflow can occur, causing std::vector ::resize to request an attacker-controlled size and quickly trigger OOM and remote process termination. Versions 3.4.1, 3
.3.1, and 2.6.11 patch the issue.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
