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`.","state":0,"publishedAt":"2026-10-20T15:19:43.014+00:00","modifiedAt":"2026-10-20T17:04:52.595+00:00","affected":[{"ecosystem":"Vendor product","name":"ThreadX","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse ThreadX\",\n                    \"packageName\": \"ThreadX\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.0.1\",\n                            \"lessThanOrEqual\": \"6.5.1.202602a\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"6.5.2.202603\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":4.8,"severity":"MEDIUM"}],"references":["https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-5w57-xhwq-v7wq"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94202","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94202","identifiers":["CVE-2026-94202"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
