CVE-2025-65566
High 7.5
In plain English
A high-severity null pointer dereference in the affected software. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 27% of all known vulnerabilities).
Official 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.
