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.","state":0,"publishedAt":"2026-05-27T15:50:18.242+00:00","modifiedAt":"2026-05-28T14:46:12.592+00:00","affected":[{"ecosystem":"Vendor product","name":"free5gc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"free5gc\",\n                    \"product\": \"free5gc\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.2.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/free5gc/free5gc/security/advisories/GHSA-wwqh-7jm5-gj7w","https://github.com/free5gc/free5gc/issues/879","https://github.com/free5gc/pcf/pull/65","https://github.com/free5gc/pcf/commit/508d70b8527a6c8c923179dad450ea01e16b6aeb"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44317","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44317","identifiers":["CVE-2026-44317"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
