CVE-2025-56568: n/a
Assertion failure vulnerability in the PCO (Protocol Configuration Options) parser in the SMF (Session Management Function) component of Open5GS before v2.7.5 allows remote attackers to cause denial of service via specially crafted NGAP messages containing malformed length fields in protocol configuration data.
AI Analysis
Technical Summary
This vulnerability involves an assertion failure in the PCO parser of the SMF component in Open5GS before version 2.7.5. Remote attackers can cause a denial of service by sending NGAP messages containing malformed length fields in protocol configuration data, which triggers the assertion failure. The vulnerability affects Open5GS deployments that process NGAP messages and use the vulnerable SMF component. No CVSS score or detailed remediation information is provided in the available data.
Potential Impact
The primary impact is a denial of service condition caused by assertion failure in the SMF component of Open5GS. This could disrupt session management functions in affected deployments, potentially impacting network availability. There is no indication of code execution or data leakage from the provided information. No known exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider monitoring for malformed NGAP messages and applying any recommended vendor mitigations once available. Avoid exposure of the vulnerable SMF component to untrusted networks if possible.
