{"id":"CVE-2026-37229","details":"FlexRIC v2.0.0 contains a reachable assertion in e2ap_create_pdu() triggered when ASN.1 PER decoding fails. A remote unauthenticated attacker can send any non-PER byte sequence (e.g., a single 0x00 byte) over SCTP to the near-RT RIC (port 36421) or iApp (port 36422) to crash the process via SIGABRT. The assertion is reached before any protocol-level validation occurs. All three E2AP protocol versions (v1.01, v2.03, v3.01) are affected.","modified":"2026-07-24T03:57:05.681668927Z","published":"2026-06-01T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37229.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37229.json"},{"type":"ADVISORY","url":"https://github.com/MinamiKotor1/oran-security-advisories-zhongnan-luo/blob/main/advisories/CVE-2026-37229.md"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-37229"},{"type":"PACKAGE","url":"https://gitlab.eurecom.fr/mosaic5g/flexric"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.eurecom.fr/mosaic5g/flexric","events":[{"introduced":"1f04cc558ebc8da9de6a620762bc02f5db4ecb4a"},{"last_affected":"1f04cc558ebc8da9de6a620762bc02f5db4ecb4a"}],"database_specific":{"cpe":"cpe:2.3:a:mosaic5g:flexric:2.0.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.0.0"},{"last_affected":"2.0.0"}],"source":"CPE_STRING"}}],"versions":["2.0.0","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-37229.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
