Vulnerability in github.com/ellanetworks/core (CVE-2026-44475)
Summary
Vulnerability in github.com/ellanetworks/core (CVE-2026-44475). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 1.10.0 or later.
Original description
The description as published by the source.
Summary
Ella Core does not verify the UE Security Capabilities received in NGAP PathSwitchRequest messages against its locally stored values. A malicious gNB can overwrite Ella Core's stored UE security capabilities for any UE with arbitrary values by sending a single crafted PathSwitchRequest.
Impact
A gNB can corrupt Ella Core's stored UE security capabilities for a target UE.
Fix
The PathSwitchRequest handler now compares the received UE Security Capabilities against Ella Core's locally stored values, preserves the stored values on mismatch, returns them in the PathSwitchRequestAcknowledge, and logs the event.
