Because the destination is recognized as a local address, both the echo request and the resulting echo reply are processed inline before the current frame returns. The nested input-path frames exceed the work-queue stack and trigger a stack overflow.","state":0,"publishedAt":"2026-05-12T05:39:02.537+00:00","modifiedAt":"2026-10-15T22:10:23.437+00:00","affected":[{"ecosystem":"Vendor product","name":"Zephyr","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageName\": \"Zephyr\",\n                    \"product\": \"Zephyr\",\n                    \"repo\": \"https://github.com/zephyrproject-rtos/zephyr\",\n                    \"vendor\": \"zephyrproject-rtos\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"4.4.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"*\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-6fcc-8rwr-w7xx"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-1681","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-1681","identifiers":["CVE-2026-1681"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
