free5gc

A vulnerability was determined in Free5GC up to 4.1.0. The impacted element is the function establishPfcpSession of the component SMF. Executing a manipulation can lead to null pointer dereference. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized. It is best practice to apply a patch to resolve this issue.

CVE-2026-1973 identifies a null pointer dereference vulnerability in the Free5GC 5G core network software, specifically within the Session Management Function (SMF) component's establishPfcpSession function. This function is responsible for establishing PFCP (Packet Forwarding Control Protocol) sessions, which are critical for managing user plane resources in 5G networks. The vulnerability arises when crafted input causes the function to dereference a null pointer, leading to a crash or denial of service (DoS) condition. The flaw can be triggered remotely over the network without requiring authentication or user interaction, making it accessible to unauthenticated attackers. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation and the impact on availability, but no direct compromise of confidentiality or integrity. Although no active exploits have been reported in the wild, the public disclosure increases the likelihood of exploitation attempts. Free5GC is an open-source 5G core network implementation used by telecom operators and research institutions globally, making this vulnerability relevant to critical 5G infrastructure. The absence of patches at the time of disclosure necessitates immediate attention to mitigate potential service disruptions.
