CVE-2026-106807 Details
Description
A denial-of-service vulnerability exists in open5GS v2.8.0 in the PFCP transaction handling path. When the PFCP transaction or timer resource pool is exhausted, ogs_pfcp_xact_remote_create() returns NULL, but the failure is not handled properly and leads to an ogs_assert(new) failure in ogs_pfcp_xact_receive(). An attacker able to send PFCP messages to the affected SMF/UPF can exhaust transaction resources and cause the network function process to terminate with SIGABRT, resulting in service disruption and preventing further session establishment until the affected component is restarted.
A denial-of-service vulnerability has been identified in Open5GS version 2.8.0, specifically within the PFCP transaction handling process. The issue arises when the PFCP transaction or timer resource pool becomes depleted. In such cases, the function 'ogs_pfcp_xact_remote_create()' returns NULL, but this failure is not properly managed. Instead, it leads to an assertion failure in 'ogs_pfcp_xact_receive()', causing the network function process to crash. This disruption prevents the establishment of new sessions until the component is restarted. The vulnerability can be exploited by sending PFCP messages to the affected SMF or UPF, exhausting transaction resources and causing the process to terminate with a SIGABRT signal.
Users can update to Open5GS version 2.8.1 or later, where this vulnerability has been addressed.
