A queue's `tx_queue_message_size` is a count of `ULONG`s and the copy moves that many words, so the extent is `message_size * sizeof(ULONG)` bytes.\n\n\n\nThe front-send dispatcher passed the word count itself. `tx_queue_send` and `tx_queue_receive`, either side of it in the same header, have always multiplied.\n\n\n\nA source buffer ending `message_size` bytes into memory the module may read was therefore accepted, and `_txe_queue_front_send` then read `message_size * sizeof(ULONG)` bytes from it in privileged mode — `3 * message_size` bytes past the end of what the module is allowed to read. The words are written into the queue's message area, so a module that can receive from that queue reads them back.","state":0,"publishedAt":"2026-10-20T14:35:40.629+00:00","modifiedAt":"2026-10-20T15:34:45.488+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-rrg6-24r9-wqpm"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-95111","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-95111","identifiers":["CVE-2026-95111"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
