{"id":"CVE-2026-85445","summary":"MOOS-IvP through 24.8.1 BHV_IPF Demultiplexer Memory Exhaustion via Packet Count","details":"MOOS-IvP through 24.8.1 contains a denial of service vulnerability in the Demuxer::addMuxPacket() function that trusts the packet count declared in mux headers without validation. Attackers can declare arbitrarily large packet counts to trigger unbounded memory allocation, exhausting system resources and causing service unavailability.","modified":"2026-09-06T08:03:30.255990Z","published":"2026-09-03T22:38:34.486Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-789"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85445.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85445.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85445"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/moos-ivp-through-24.8.1-bhv-ipf-demultiplexer-memory-exhaustion-via-packet-count"},{"type":"FIX","url":"https://github.com/moos-ivp/moos-ivp/commit/fc5649ac12915f66a9f09520cdb6b14bc6d77595"},{"type":"FIX","url":"https://github.com/moos-ivp/moos-ivp/pull/129"},{"type":"PACKAGE","url":"https://github.com/moos-ivp/moos-ivp"},{"type":"ARTICLE","url":"https://github.com/moos-ivp/moos-ivp/blob/1de9ae146cd63c209e8c3fd81611a4ed2472971b/ivp/src/lib_ivpbuild/Demuxer.cpp#L79"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/moos-ivp/moos-ivp","events":[{"introduced":"0"},{"fixed":"477be7e91bf220185d55e5a2a9dba16dbde32c3f"},{"fixed":"fc5649ac12915f66a9f09520cdb6b14bc6d77595"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"24.8.1"}],"source":["DESCRIPTION","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85445.json","vanir_signatures_modified":"2026-09-06T08:03:30Z","vanir_signatures":[{"deprecated":false,"digest":{"function_hash":"205105793825430045765894660149070176882","length":721},"id":"CVE-2026-85445-17eb9c04","signature_type":"Function","signature_version":"v1","source":"https://github.com/moos-ivp/moos-ivp/commit/477be7e91bf220185d55e5a2a9dba16dbde32c3f","target":{"file":"ivp/src/lib_mbutil/ReleaseInfo.cpp","function":"showReleaseInfo"}},{"digest":{"line_hashes":["71475089026327374911439190140854268963","288109013441206453595364179806630758895","108583411300907172617501463823770114997","17171581118612079636848717634386598063"],"threshold":0.9},"id":"CVE-2026-85445-703d642b","signature_type":"Line","signature_version":"v1","source":"https://github.com/moos-ivp/moos-ivp/commit/477be7e91bf220185d55e5a2a9dba16dbde32c3f","target":{"file":"ivp/src/pMarineViewer/main.cpp"},"deprecated":false},{"deprecated":false,"digest":{"function_hash":"118965062358282729215132681048895208743","length":2942},"id":"CVE-2026-85445-9c0df7cc","signature_type":"Function","signature_version":"v1","source":"https://github.com/moos-ivp/moos-ivp/commit/477be7e91bf220185d55e5a2a9dba16dbde32c3f","target":{"file":"ivp/src/pMarineViewer/main.cpp","function":"main"}},{"target":{"file":"ivp/src/lib_mbutil/ReleaseInfo.cpp"},"deprecated":false,"digest":{"line_hashes":["221566291563585211413467636629101977597","69881209764151303531923320257498233409","153719805825789704065453832941046288979","196362707078072643545117675400601289962"],"threshold":0.9},"id":"CVE-2026-85445-b57c450a","signature_type":"Line","signature_version":"v1","source":"https://github.com/moos-ivp/moos-ivp/commit/477be7e91bf220185d55e5a2a9dba16dbde32c3f"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
