{"id":"CVE-2026-85443","summary":"MOOS core-moos through 10.4.0 MOOSDB Accept Loop Denial of Service","details":"MOOS core-moos through 10.4.0 contains a denial of service vulnerability in MOOSCommServer::ListenLoop() where the accept thread performs a blocking receive without timeout during the wire-protocol handshake. An attacker can open a TCP connection to the MOOSDB port and send no data, causing the accept thread to block indefinitely while holding the socket-list lock, preventing all subsequent client connections.","modified":"2026-09-05T03:48:30.300108885Z","published":"2026-09-03T22:38:33.200Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85443.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85443.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85443"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/moos-core-moos-through-10.4.0-moosdb-accept-loop-denial-of-service"},{"type":"FIX","url":"https://github.com/themoos/core-moos/commit/8d940303949a850d4625eca2a60f27adee9c3ec4"},{"type":"FIX","url":"https://github.com/themoos/core-moos/pull/83"},{"type":"PACKAGE","url":"https://github.com/themoos/core-moos"},{"type":"ARTICLE","url":"https://github.com/themoos/core-moos/blob/ec9c77c68fcbdef8f5e4c60fe243acd223433f0c/Core/libMOOS/Comms/MOOSCommServer.cpp#L922"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/themoos/core-moos","events":[{"introduced":"0"},{"fixed":"19d06a9aefc910b0504c2c8589b1403f3b6e77a8"},{"fixed":"8d940303949a850d4625eca2a60f27adee9c3ec4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"10.4.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v10.0.4-alpha","10.0.3-devel-candidate","10.0.2-devel","10.0.1-devel","PreProfilingmerge","IvPCompatibility"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85443.json"}}],"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"}]}
