Summary

CVE-2024-10838 is a high-severity Wrap or Wraparound (CWE-191) vulnerability in Eclipse Cyclone Data Distribution Service. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 43% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-10838, published on 2025-03-12, is an integer underflow vulnerability (CWE-191) affecting Eclipse CycloneDDS. The flaw occurs during deserialization and enables out-of-bounds reads of heap memory, potentially incorporating secret data or pointers that reveal the address space layout into deserialized data structures.

Any unauthenticated attacker can exploit this vulnerability remotely over the network with low attack complexity, as indicated by its CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H). Successful exploitation may leak sensitive information via confidentiality impacts or trigger thread crashes and denial-of-service conditions through availability impacts.

Advisories and patches are detailed in Eclipse CycloneDDS resources, including the GitHub security advisory (GHSA-6jj6-w25p-jc42) and release tag 0.10.5, with CVE assignment tracked at Eclipse GitLab issue 46. Security practitioners should review these for mitigation guidance, such as updating to the patched version.
