      "value": "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.\n"

Esto puede bloquear de forma remota cualquier proceso Fast-DDS. La llamada a free() podr\u00eda potencialmente dejar el puntero en el control del atacante, lo que podr\u00eda conducir a un doble free.
