CVE-2026-8224: Denial of Service in Open5GS
CVE-2026-8224 is a medium severity denial of service vulnerability in Open5GS versions up to 2. 7. 7. The issue exists in the function pcf_sess_set_ipv6prefix within the PCF component, where manipulation of the SmPolicyContextData. ipv6AddressPrefix argument can cause a denial of service. The vulnerability can be exploited remotely without authentication. Although the exploit has been publicly disclosed, there is no vendor response or official patch available at this time.
AI Analysis
Technical Summary
This vulnerability affects Open5GS up to version 2.7.7 in the PCF component's pcf_sess_set_ipv6prefix function. By manipulating the SmPolicyContextData.ipv6AddressPrefix argument, an attacker can remotely trigger a denial of service condition. The vulnerability does not require privileges or user interaction to exploit and has a CVSS 4.0 base score of 6.9, indicating medium severity. The vendor has not provided any advisory or patch, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation results in denial of service, potentially disrupting the availability of the affected Open5GS PCF component. This could impact network policy control functions relying on the PCF, leading to service interruptions. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or vendor response is available, users should monitor for updates from the Open5GS project. In the meantime, consider applying network-level protections to limit exposure of the PCF component to untrusted networks.
