{"id":"CVE-2026-94023","summary":"Module delete dispatchers do not enforce kernel-object ownership before irreversible deletion","details":"A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for *using* an object, and using an object a module does not own is supported and intended — `txm_module_object_pointer_get_extended` searches the system's created objects by name and hands back objects the application created and objects other modules created, so that a module can send to a shared queue, take a shared semaphore or get a shared mutex.\n\n\n\nDestroying one of those is not sharing it. A module could name any object it had a pointer to and have the privileged dispatcher delete it.","aliases":["GHSA-36vf-7cx6-9f9j"],"modified":"2026-10-21T03:00:18.192366911Z","published":"2026-10-20T15:18:09.957Z","database_specific":{"cna_assigner":"eclipse","cwe_ids":["CWE-125","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/94xxx/CVE-2026-94023.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/94xxx/CVE-2026-94023.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-36vf-7cx6-9f9j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94023"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/threadx","events":[{"introduced":"6a018a4cfda937c0d8cbdee761187c5c5843e115"},{"last_affected":"b91b03b9e75fa523b17127f9e0eca09dca916459"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"6.0.1"},{"last_affected":"6.5.1.202602a"}],"source":"AFFECTED_FIELD"}]}}],"versions":["v6.4.1_rel","v6.5.1.202602a_rel","v6.5.1.202602_rel","v6.5.0.202601_rel","v6.4.5.202504_rel","v6.4.3.202503_rel","v6.4.2_rel","v6.4.0_rel","v6.3.0_rel","v6.2.1_rel","v6.2.0_rel","v6.1.12_rel","v6.1.11_rel","v6.1.10_rel","v6.1.9_rel","v6.1.8_rel","v6.1.7_rel","v6.1.6_rel","v6.1.5_rel","v6.1.3_rel","v6.1.2_rel","v6.1.1_rel","v6.1_rel","v6.0.2_rel","v6.0.1_rel"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-94023.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
