CVE-2026-34761: CWE-476: NULL Pointer Dereference in ellanetworks core
Ella Core is a 5G core designed for private networks. Prior to version 1.8.0, Ella Core panics when processing a NGAP handover failure message. An attacker able to cause a gNodeB to send NGAP handover failure messages to Ella Core can crash the process, causing service disruption for all connected subscribers. This issue has been patched in version 1.8.0.
AI Analysis
Technical Summary
Ella Core versions before 1.8.0 contain a NULL pointer dereference vulnerability (CWE-476) triggered by processing NGAP handover failure messages. This leads to a process panic and service disruption. The vulnerability requires an attacker to cause a gNodeB to send crafted NGAP handover failure messages to the core. The vulnerability has a CVSS 3.1 base score of 5.8, reflecting a medium severity with network attack vector, high attack complexity, and requiring high privileges. The issue is fixed in version 1.8.0.
Potential Impact
Successful exploitation causes the Ella Core process to crash, resulting in denial of service and disruption of connectivity for all subscribers relying on the affected core. There is no impact on confidentiality or integrity reported. The disruption affects availability only.
Mitigation Recommendations
Upgrade Ella Core to version 1.8.0 or later, where this NULL pointer dereference vulnerability has been patched. No other mitigations are indicated or required as the fix is available and official.
