AI Analysis
Technical Summary
CVE-2026-10117 is a denial of service vulnerability affecting Open5GS versions 2.7.0 through 2.7.7. The issue resides in the ogs_pool_id_calloc function in the /lib/sbi/nghttp2-server.c library. An attacker can remotely manipulate this function to cause a denial of service condition. The vulnerability has been publicly disclosed, and exploit code is available. The CVSS 4.0 base score is 5.3, indicating medium severity. No vendor advisory or patch information is currently available, and the product is not a cloud service.
Potential Impact
Successful exploitation results in denial of service, causing the Open5GS service to become unavailable. This can disrupt network functions relying on Open5GS. There is no indication of privilege escalation, data confidentiality, or integrity impact. The vulnerability can be exploited remotely without user interaction and requires low attack complexity with low privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround is currently documented, it is recommended to monitor vendor communications for updates. Until a fix is available, consider limiting exposure of the affected service to untrusted networks to reduce risk.
