Name of the Vulnerable Software and Affected Versions omec-project UPF versions up to 2.1.3-dev

Description A denial-of-service issue exists in the UPF (component upf-epc/pfcpiface). When the UPF receives a PFCP Association Setup Request lacking the mandatory NodeID Information Element, the association setup handler attempts to use a null pointer without validation, leading to a process termination. An attacker capable of sending PFCP Association Setup Request messages to the UPF’s N4/PFCP endpoint can repeatedly crash the UPF and disrupt user-plane services. The affected component is upf-epc/pfcpiface.

Recommendations Versions prior to 2.1.3-dev should be updated.
