After PFCP association, a specially crafted PFCP Session Establishment Request with a CreatePDR that contains a malformed Flow-Description is not robustly validated. The Flow-Description parser (parseFlowDesc) can read beyond the bounds of the provided buffer, causing a panic and terminating the UPF process. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF."}], "lastModified": "2026-01-07T21:06:42.410", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:opennetworking:upf:2.1.3:dev:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E580395D-12BF-4D0A-AA6F-FD59C36E1EED"}], "operator": "OR"}]}], "sourceIdentifier": "[email protected]"}
