A denial of service vulnerability (CVSS 7.1) that allows a remote attacker. Risk factors: public PoC available.

A buffer overflow vulnerability (CVSS 7.8) that allows a local attacker. Risk factors: public PoC available.

Buffer overflow vulnerability in the PFCP (Packet Forwarding Control Protocol) library used by open5gs 2.7.2 and earlier. The vulnerability exists in the `ogs_pfcp_dev_add` function due to missing length validation on the `session.dev` field, allowing a local attacker with low privileges to cause a buffer overflow that can result in information disclosure, integrity compromise, or denial of service. The vulnerability has not been reported as actively exploited in the wild (no KEV status indicated), but the low attack complexity and local attack vector make it a practical concern for compromised or insider threat scenarios.

A vulnerability was found in Open5GS up to 2.7.3. It has been declared as problematic. Affected by this vulnerability is the function common_register_state of the file src/mme/emm-sm.c of the component AMF/MME. The manipulation of the argument ran_ue_id leads to denial of service. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of the patch is 62cb99755243c9c38e4c060c5d8d0e158fe8cdd5. It is recommended to apply a patch to fix this issue.
