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.","published":"2026-09-03T22:38:29.903Z","modified":"2026-09-03T22:38:29.903Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/moos-ivp/moos-ivp/pull/126","label":"moos-ivp/moos-ivp#126"},"references":[{"type":"FIX","url":"https://github.com/moos-ivp/moos-ivp/pull/126"},{"type":"FIX","url":"https://github.com/moos-ivp/moos-ivp/commit/85f4653ff792b30c3ab14dc0eac0991d1405d904"},{"type":"WEB","url":"https://github.com/moos-ivp/moos-ivp"},{"type":"WEB","url":"https://github.com/moos-ivp/moos-ivp/blob/1de9ae146cd63c209e8c3fd81611a4ed2472971b/ivp/src/lib_ivpbuild/FunctionEncoder.cpp#L407"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/moos-ivp-through-24.8.1-out-of-bounds-write-via-unvalidated-ivp-payload-counts"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-03T22:38:29.903Z"}}
