CVE-2026-85438
MOOS-IvP buffer overflow in BHV_IPF parsing enabling potential remote code execution
Is CVE-2026-85438 being exploited?
Not confirmed. CVE-2026-85438 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

What does CVE-2026-85438 affect?
CVE-2026-85438 affects MOOS-IvP <= 24.8.1, ivpbuild/FunctionEncoder (StringToIvPFunction), Autonomous marine/robotic platforms using MOOS-IvP. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-85438?
Update to patched MOOS-IvP or apply upstream commit; block/untrusted BHV_IPF inputs.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Crafted BHV_IPF payloads can trigger out-of-bounds write to IvPBox weights, enabling memory corruption and potential remote code execution.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
