{"id":"CVE-2026-102709","details":"Improper validation of non-secure (NS) pointers in multiple TrustZone-M non-secure callable (NSC) entry functions allows an attacker executing in the non-secure world to supply pointers to secure memory. The secure firmware subsequently dereferences these attacker-controlled pointers without verifying that they reference non-secure memory, resulting in unintended disclosure of secure memory contents. This violates the isolation guarantees provided by Arm TrustZone-M and can be leveraged as a memory disclosure or corruption primitive that may enable recovery of sensitive cryptographic material.","aliases":["GHSA-ffg5-m7vh-vwrp"],"modified":"2026-10-02T03:30:31.104546659Z","published":"2026-09-29T17:36:17.135Z","database_specific":{"cna_assigner":"eclipse","cwe_ids":["CWE-200","CWE-501","CWE-822"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102709.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102709.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-ffg5-m7vh-vwrp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102709"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/threadx","events":[{"introduced":"0"},{"last_affected":"b91b03b9e75fa523b17127f9e0eca09dca916459"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"6.5.1.202602"}],"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","v6.0_rel"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-102709.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:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
