CVE-2025-64098

Severity CVSS v4.0:
LOW
Type:
CWE-125 Out-of-bounds Read
Publication date:

Description

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group<br /> ). 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 <br /> SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t<br /> he fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage are tampered with — specifically by ta<br /> mpering with the the `vecsize` value read by `readOctetVector` — a 32-bit integer overflow can occur, causing `std::vector<br /> ::resize` to request an attacker-controlled size and quickly trigger OOM and remote process termination. Versions 3.4.1, 3<br /> .3.1, and 2.6.11 patch the issue.
