Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). In affected versions specific DATA submessages can be sent to a discovery locator which may trigger a free error. This can remotely crash any Fast-DDS process. The call to free() could potentially leave the pointer in the attackers control which could lead to a double free. This issue has been addressed in versions 2.12.0, 2.11.3, 2.10.3, and 2.6.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
