Attack-Flow Graph

Executive Summary

This vulnerability is a flaw in the omec-project UPF software (up to version 2.1.3-dev) in the function handleSessionEstablishmentRequest. It causes a null pointer dereference, which means the program tries to access or manipulate data through a pointer that is not properly initialized, leading to a crash or unexpected behavior. The flaw exists in the PFCP Session Establishment Request Handler component and can be exploited remotely.

Impact Analysis

The vulnerability can cause the affected software to crash or behave unexpectedly due to the null pointer dereference. Since the attack can be initiated remotely, it may lead to denial of service or disruption of the network functions relying on the omec-project UPF component. This could impact availability of services dependent on this software.
