Gửi #774073: Linux Foundation free5GC 4.1.0 Denial of Servicethông tin

tiêu đềLinux Foundation free5GC 4.1.0 Denial of Service
Mô tảfree5GC AMF crashes when it receives an out-of-sequence NAS message during the registration procedure. Specifically, after the AMF enters the state Waiting for IdentityResponse (after processing Security Mode Complete), sending a UplinkNASTransport that carries a Registration Complete NAS message causes the AMF process to crash. This appears to be a missing state/transition validation (or missing nil/defensive checks) for handling Registration Complete when the UE has not yet completed the expected Identity Response step.
