{"schemaVersion":3,"id":"CVE-2025-65566","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Session Report Response that is missing the mandatory Cause Information Element, the session report handler dereferences a nil pointer instead of rejecting the malformed message. This triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Report Response messages to the UPF's N4/PFCP endpoint can exploit this flaw to repeatedly crash the UPF and disrupt user-plane services.","dates":{"published":"2025-12-18T00:00:00.000Z","modified":"2025-12-19T18:00:58.688Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00338,"percentile":0.25798,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00338},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00338,"percentile":0.25798}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00338,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":
