Name of the Vulnerable Software and Affected Versions free5GC version 4.0.1

Description An improper input validation and protocol compliance issue exists in free5GC version 4.0.1. The UPF component incorrectly accepts a malformed PFCP Association Setup Request, violating 3GPP TS 29.244. This leads to an inconsistent state within the UPF, and a subsequent valid PFCP Session Establishment Request causes a cascading failure, disrupting the SMF connection and resulting in service degradation. The vulnerability allows remote attackers to cause a denial of service.

Recommendations Update to a newer version that contains a fix for this vulnerability.
