An issue was discovered in Open5GS v2.7.2. When a UE switches between two gNBs and sends a handover request at a specific time, it may cause an exception in the AMF's internal state machine, leading to an AMF crash and resulting in a Denial of Service (DoS).

A missing length check in ogspfcpdevadd function from PFCP library, used by both smf and upf in open5gs 2.7.2 and earlier, allows a local attacker to cause a Buffer Overflow by changing the session.dev field with a value with length greater than 32.
