SCA: security update for github.com/free5gc/pcf (GHSA-wwqh-7jm5-gj7w)

medium Tenable Cloud Security Plugin ID 441582

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 PCF POST /npcf-
 policyauthorization/v1/app-sessions handler panics on a single authenticated request whose
 ascReqData.suppFeat == "1" (enabling traffic-routing feature negotiation) and whose medComponents entries
 supply an afAppId but NO AfRoutReq. The create path then calls provisioningOfTrafficRoutingInfo(smPolicy,
 appID, routeReq, ...) with routeReq == nil and dereferences routeReq.RouteToLocs (and other fields)
 without a nil check, causing runtime error: invalid memory address or nil pointer dereference. Gin
 recovery converts the panic into HTTP 500. This vulnerability is fixed in 4.2.2. (CVE-2026-44317)

Solution

Update the github.com/free5gc/pcf library and its related packages to version 1.4.3 or later.
