Description

A heap buffer overflow vulnerability in the UPF component of free5GC v4.0.1 allows remote attackers to cause a denial of service via a crafted PFCP Session Modification Request. The issue occurs in the SDFFilterFields.UnmarshalBinary function (sdf-filter.go) when processing a declared length that exceeds the actual buffer capacity, leading to a runtime panic and UPF crash.
