The issue occurs in CreateCommonPacketFormatStructure() when it parses recognized optional socket address information items of type 0x8000 or 0x8001 without first validating that the remaining CPF buffer contains the complete fixed sockaddr structure. This allows a remote attacker to cause a denial of service.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-125"],"references":["https://github.com/EIPStackGroup/OpENer/blob/master/source/src/enet_encap/cpf.c","https://github.com/EIPStackGroup/OpENer/blob/master/source/src/enet_encap/encap.c","https://github.com/EIPStackGroup/OpENer/blob/master/source/src/enet_encap/endianconv.c","https://github.com/EIPStackGroup/OpENer/issues/573","https://github.com/EIPStackGroup/OpENer/issues/573"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-75348","score":0.00505,"percentile":0.42863,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
