Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.
In a few clicks we can analyze your entire application and see what components are vulnerable in your application, and suggest you quick fixes.

Affected versions of this package are vulnerable to Use After Free due to an invalid DATA_FRAG Submessage causing a bad-free error, allowing for the remote termination of the Fast-DDS process. If an invalid Data_Frag packet is sent, the Inline_qos, SerializedPayload member of object ch will attempt to release memory without initialization, leading to a 'bad-free' error.
