SCA: security update for github.com/free5gc/nef (GHSA-rxrq-fv76-26pr)

high Tenable Self-Hosted Container Security Plugin ID 441589

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's NEF terminates
 the entire process when a stored PFD-subscription notifyUri cannot be reached. In
 PfdChangeNotifier.FlushNotifications(), the notifier calls NnefPFDmanagementNotify(...) and on any
 delivery error invokes logger.PFDManageLog.Fatal(err), which is os.Exit(1)-equivalent in Go. An attacker
 who can create a PFD subscription with an attacker-chosen notifyUri and then trigger a PFD change can
 deterministically kill NEF on the asynchronous delivery attempt -- the process exits with status 1,
 dropping NEF's entire SBI surface until restart. This vulnerability is fixed in 4.2.2. (CVE-2026-44319)

Solution

Update the github.com/free5gc/nef library and its related packages to version 1.2.3 or later.
