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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-190"],"references":["https://github.com/moos-ivp/moos-ivp","https://github.com/moos-ivp/moos-ivp/blob/1de9ae146cd63c209e8c3fd81611a4ed2472971b/ivp/src/lib_ivpbuild/FunctionEncoder.cpp#L407","https://github.com/moos-ivp/moos-ivp/commit/85f4653ff792b30c3ab14dc0eac0991d1405d904","https://github.com/moos-ivp/moos-ivp/pull/126","https://www.vulncheck.com/advisories/moos-ivp-through-24.8.1-out-of-bounds-write-via-unvalidated-ivp-payload-counts"],"products":["mit:moos-ivp"],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-85438","score":0.01086,"percentile":0.65032,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
