Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-404: Improper Resource Shutdown or Release, where the product does not release or incorrectly releases a resource before it is made available for re-use. In Github.com/omec project/amf, 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

A security vulnerability has been detected in omec-project amf up to 2.1.3-dev. This impacts the function UERadioCapabilityCheckResponse of the file ngap/dispatcher.go. Such manipulation leads to null pointer dereference. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 2.2.0 will fix this issue. Upgrading the affected component is advised. The same pull request fixes multiple security issues.
