Answer in brief
CVE-2026-85438 records a Critical severity (CVSS 9.8) vulnerability in MOOS-IvP through 24.8.1 Out-of-Bounds Write via Unvalidated IvP Payload Counts. The current sources do not mark it as known exploited. The current feed maps moos-ivp/moos-ivp (generic), moos-ivp/moos-ivp (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

MOOS-IvP through 24.8.1 contains a buffer overflow vulnerability in StringToIvPFunction() where dimension, piece, and degree counts from encoded BHV_IPF payloads are used as allocation sizes and loop bounds without validation. Attackers can supply crafted payloads with mismatched dimension values to write attacker-controlled doubles past the end of the IvPBox weight array, causing memory corruption and potential code execution.
