CVE-2026-10565: Race Condition in Open5GS
CVE-2026-10565 is a race condition vulnerability in Open5GS versions up to 2. 7. 6, specifically in the gmm_state_security_mode function within the NGAP Handover component. The vulnerability can be triggered remotely but requires high attack complexity and has low exploitability. Although an exploit has been publicly released, no official patch or remediation has yet been accepted. The CVSS score is low, indicating limited impact potential.
AI Analysis
Technical Summary
This vulnerability involves a race condition in the gmm_state_security_mode function of the src/amf/gmm-sm.c file in Open5GS (up to version 2.7.6). The flaw exists in the NGAP Handover component and can be triggered remotely, though the attack complexity is high and exploitability is difficult. A public exploit is available, but the fix is pending acceptance via a pull request. No official remediation or patch has been released at this time.
Potential Impact
The vulnerability could potentially allow an attacker to cause unintended behavior in the NGAP Handover process due to the race condition. However, the low CVSS score (2.3) and the high complexity required for exploitation limit the practical impact. There is no indication of privilege escalation, denial of service, or data confidentiality/integrity compromise from the provided data.
Mitigation Recommendations
No official patch or remediation is currently available. A pull request containing a fix exists but awaits acceptance. Users should monitor the Open5GS project for updates and apply the fix once it is officially released. Given the high complexity and low exploitability, immediate urgent action is not indicated, but vigilance is recommended.
