CVE-2026-37224: n/a
FlexRIC v2.0.0 contains a vulnerability where the iApp process crashes upon receiving duplicate E2_SETUP_REQUEST messages from the same or spoofed E2 Node. This occurs because the node ID uniqueness is enforced using assert() instead of graceful rejection, leading to a process abort (SIGABRT). The vulnerability can be triggered remotely by an unauthenticated attacker sending two identical setup requests, causing a denial of service.
AI Analysis
Technical Summary
CVE-2026-37224 describes a denial-of-service vulnerability in FlexRIC v2.0.0. The iApp process listening on port 36421 crashes when it receives duplicate E2_SETUP_REQUEST messages with the same E2 node configuration. The root cause is the use of assert() to enforce node ID uniqueness, which causes the process to abort instead of handling the duplicate request gracefully. This allows a remote unauthenticated attacker to crash the service by sending two such requests, resulting in a denial of service condition.
Potential Impact
An unauthenticated remote attacker can cause the FlexRIC iApp process to crash, resulting in denial of service. There is no impact on confidentiality or integrity reported. The service disruption could affect availability of the affected component until it is restarted.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Until a patch is available, monitoring and restricting access to port 36421 may help reduce exposure.
