{"id":"CVE-2026-94202","summary":"Module block-pool create validates two of the four parameter words it reads","details":"The Module Manager's block-pool create dispatcher proved that two `ALIGN_TYPE` words of the extra-parameter array a memory-protected module supplies lay inside the module's data, and then used indices 0 through 3 of that array.\n\n\n\nOne of the two unproved words is read by the dispatcher's own buffer check, which takes index 1 as the pool start and index 2 as the length to range-check it over. So the out-of-bounds read is performed by the validation code itself, before the kernel service is reached, and the size the caller's pool start is then validated against is a word the manager has not proved the module owns. The other unproved word is read when the service's argument list is built.\n\n\n\nVulnerable function: `_txm_module_manager_tx_block_pool_create_dispatch`, in `common_modules/module_manager/inc/txm_module_manager_dispatch.h`.","aliases":["GHSA-5w57-xhwq-v7wq"],"modified":"2026-10-21T03:00:18.994864778Z","published":"2026-10-20T15:19:43.014Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/94xxx/CVE-2026-94202.json","cna_assigner":"eclipse","cwe_ids":["CWE-125"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/94xxx/CVE-2026-94202.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-5w57-xhwq-v7wq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94202"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/threadx","events":[{"introduced":"6a018a4cfda937c0d8cbdee761187c5c5843e115"},{"last_affected":"b91b03b9e75fa523b17127f9e0eca09dca916459"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"6.0.1"},{"last_affected":"6.5.1.202602a"}]}]}}],"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-2026-94202.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:L/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
