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."}], "lastModified": "2026-01-06T16:18:14.383", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:linuxfoundation:upf:2.1.3:dev:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F5D98CF2-1D67-4E3A-B8AA-6B5F6D2FF666"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
