Technical details
The vulnerability is an improper input validation flaw in the NGSetupRequest handler of Magma's AMF component. When processing an NGAP (NG Application Protocol) message with the NG-IoT-DefaultPagingDRX parameter set, the AMF decoder throws an error instead of ignoring the optional field as per specification. This occurs even though the parameter has its Criticality flag set to "ignore," meaning compliant implementations should proceed without error. An attacker or non-compliant gNB can trigger this decoder error remotely via crafted SCTP-transported NGAP messages, causing the AMF to reject legitimate setup requests and disrupting network connectivity.
