Technical details
A NULL pointer dereference (CWE-476) exists in the NGAP handover handlers of Ella Core. The vulnerability is triggered when the core processes a malformed or specific NGAP handover failure message sent from a gNodeB (base station). An attacker with sufficient privileges to control or influence a gNodeB can send these messages to cause a process panic (crash). This results in a complete denial of service for the 5G core and its connected User Equipment (UE). The issue is fixed in version 1.8.0 by improving guards and validation within the NGAP handover handlers.
