{"id":"CVE-2026-11576","details":"The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption.","modified":"2026-07-08T07:59:44.856627732Z","published":"2026-06-19T08:27:59.652Z","database_specific":{"cna_assigner":"eclipse","cwe_ids":["CWE-415","CWE-459","CWE-908"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/11xxx/CVE-2026-11576.json"},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/123"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/11xxx/CVE-2026-11576.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11576"},{"type":"PACKAGE","url":"https://github.com/eclipse-threadx/netxduo"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/netxduo","events":[{"introduced":"bd5d12e9e601015a560b2e3bef0e78d63fc0d6c3"},{"last_affected":"8b6e03ac30ab688bec02c69d42f2304b7f72a202"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:eclipse:threadx_netx_duo:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"6.4.2"},{"last_affected":"6.5.0.202601"}]}}],"versions":["v6.5.0.202601_rel","v6.4.5.202504_rel","v6.4.4.202503a","v.6.4.4.202503_rel","v6.4.3_rel","v6.4.2_rel"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-11576.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
