AI-powered analysis for quick understanding

This vulnerability allows remote attackers to crash the UPF component of free5GC, causing a denial of service by sending a specially crafted request that tricks the system into trying to use more memory than it can handle. To exploit this, the attacker needs to send a specific type of message that exceeds the expected size, leading to a system failure.

Technical 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.
