When the UPF receives a PFCP Association Setup Request that is missing the mandatory NodeID Information Element, the association setup handler dereferences a nil pointer instead of validating the message, causing a panic and terminating the UPF process. An attacker who can send PFCP Association Setup Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.\n\n## Affected\n\n- `upf <= 2.1.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
