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).
The code does not sufficiently manage its control flow during execution, creating conditions in which the control flow can be modified in unexpected ways.
https://cwe.mitre.org/data/definitions/691.html →Open in CWE collection →This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
