| CVE-2026-26024 | 1 Free5gc | 1 Smf | 2026-02-24 | N/A |
| free5GC SMF provides Session Management Function for free5GC, an open-source project for 5th generation (5G) mobile core networks. In versions up to and including 1.4.1, SMF panics and terminates when processing a malformed PFCP SessionReportRequest on the PFCP (UDP/8805) interface. No known upstream fix is available, but some workarounds are available. ACL/firewall the PFCP interface so only trusted UPF IPs can reach SMF (reduce spoofing/abuse surface); drop/inspect malformed PFCP SessionReportRequest messages at the network edge where feasible, and/or add recover() around PFCP handler dispatch to avoid whole-process termination (mitigation only). | ||||

| CVE-2026-25501 | 1 Free5gc | 1 Smf | 2026-02-24 | N/A |
| free5GC SMF provides Session Management Function for free5GC, an open-source project for 5th generation (5G) mobile core networks. In versions up to and including 1.4.1, SMF panics due to nil pointer dereference and the SMF process terminates. This is triggered by a malformed PFCP SessionReportRequest on the SMF PFCP (UDP/8805) interface. No known upstream fix is available, but some workarounds are available. ACL/firewall the PFCP interface so only trusted UPF IPs can reach SMF (reduce spoofing/abuse surface); drop/inspect malformed PFCP SessionReportRequest messages at the network edge where feasible, and/or add recover() around PFCP handler dispatch to avoid whole-process termination (mitigation only). | ||||
| CVE-2025-69232 | 1 Free5gc | 2 Smf, Upf | 2026-02-24 | N/A |
| free5GC is an open-source project for 5th generation (5G) mobile core networks. free5GC go-upf versions up to and including 1.2.6, corresponding to free5gc smf up to and including 1.4.0, have an Improper Input Validation and Protocol Compliance vulnerability leading to Denial of Service. Remote attackers can disrupt core network functionality by sending a malformed PFCP Association Setup Request. The UPF incorrectly accepts it, entering an inconsistent state that causes subsequent legitimate requests to trigger SMF reconnection loops and service degradation. All deployments of free5GC using the UPF and SMF components may be affected. As of time of publication, a fix is in development but not yet available. No direct workaround is available at the application level. Applying the official patch, once released, is recommended. | ||||
| CVE-2026-1684 | 1 Free5gc | 2 Free5gc, Smf | 2026-02-23 | 5.3 Medium |
| A vulnerability was found in Free5GC SMF up to 4.1.0. Affected by this issue is the function HandleReports of the file /internal/context/pfcp_reports.go of the component PFCP UDP Endpoint. The manipulation results in denial of service. The attack can be executed remotely. It is advisable to implement a patch to correct this issue. | ||||
| CVE-2026-1683 | 1 Free5gc | 2 Free5gc, Smf | 2026-02-23 | 5.3 Medium |
| A vulnerability has been found in Free5GC SMF up to 4.1.0. Affected by this vulnerability is the function HandlePfcpSessionReportRequest of the file internal/pfcp/handler/handler.go of the component PFCP. The manipulation leads to denial of service. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. To fix this issue, it is recommended to deploy a patch. | ||||
| CVE-2026-1682 | 1 Free5gc | 2 Free5gc, Smf | 2026-02-23 | 5.3 Medium |
| A flaw has been found in Free5GC SMF up to 4.1.0. Affected is the function HandlePfcpAssociationReleaseRequest of the file internal/pfcp/handler/handler.go of the component PFCP UDP Endpoint. Executing a manipulation can lead to null pointer dereference. The attack may be launched remotely. The exploit has been published and may be used. A patch should be applied to remediate this issue. | ||||
| CVE-2023-47346 | 1 Free5gc | 3 Free5gc, Smf, Upf | 2024-11-21 | 7.5 High |
| 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. | ||||
