How to Fix CVE-2026-44475

To remediate this vulnerability, upgrade all affected Github.com/ellanetworks/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/ellanetworks/core fixed: 1.10.0
Upgrade github.com/ellanetworks/core to 1.10.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/ellanetworks/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-44475, inspect your project dependencies for Github.com/ellanetworks/core:

inspect dependencies for github.com/ellanetworks/core

Analyze the terminal output to locate any version of Github.com/ellanetworks/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-358: Improperly Implemented Security Check for Standard, where the product does not implement or incorrectly implements one or more security-relevant checks as specified by the design of a standardized algorithm, protocol, or technique. In Github.com/ellanetworks/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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.
