Remote denial-of-service in the omec-project UPF (pfcpiface component, version upf-epc-pfcpiface 2.1.3-dev) lets any endpoint able to reach the N4/PFCP interface crash the user-plane function by sending a malformed PFCP Session Establishment Request. The request carries a CreateFAR IE with an empty or truncated IPv4 address; parseFAR() passes it to ip2int(), which reads past the buffer and triggers a Go index-out-of-range panic (CWE-125). Publicly available exploit references exist via the upstream issue tracker, though EPSS remains low (0.46%) and it is not on CISA KEV.
Buffer Overflow vulnerability in free5gc 3.3.0, UPF 1.2.0, and SMF 1.2.0 allows attackers to cause a denial of service via crafted PFCP messages. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
