CVE-2026-8252 Details
Description
A vulnerability was determined in Open5GS up to 2.7.7. Affected is the function smf_nsmf_handle_create_data_in_hsmf of the component SMF. Executing a manipulation can lead to null pointer dereference. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
A null pointer dereference vulnerability has been identified in Open5GS versions through 2.7.7, specifically within the SMF component's function 'smf_nsmf_handle_create_data_in_hsmf'. The vulnerability arises when a 'PduSessionCreateData' request is sent without the 'vcnTunnelInfo' field. The SMF component crashes due to the missing information, as the code improperly handles the absence of 'vcnTunnelInfo' by attempting to log an error, which inadvertently leads to a crash. This issue can be exploited remotely, causing the SMF process to exit unexpectedly.
