CVE-2026-37226: n/a
FlexRIC v2. 0. 0 contains a vulnerability where the iApp process crashes upon receiving an E42_RIC_SUBSCRIPTION_REQUEST referencing a non-existent E2 Node. The crash occurs because the lookup function returns NULL, which triggers an assert failure in Debug builds and a segmentation fault in Release builds. This can be exploited remotely by an unauthenticated attacker sending a specially crafted subscription request to port 36422, causing a denial of service by crashing the iApp process.
AI Analysis
Technical Summary
The vulnerability in FlexRIC v2.0.0 arises when the iApp component processes an E42_RIC_SUBSCRIPTION_REQUEST message that references a global_e2_node_id not present in the system. The lookup function returns NULL for the missing node, which leads to an assert() failure in Debug builds (causing SIGABRT) and a NULL pointer dereference in Release builds (causing SIGSEGV). This allows a remote unauthenticated attacker to crash the iApp process by sending a malicious subscription request to port 36422, resulting in a denial of service condition.
Potential Impact
An attacker can remotely cause the iApp process to crash, leading to denial of service. There is no indication of code execution or data compromise from the provided information. The attack requires no authentication and targets the iApp process listening on port 36422.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to port 36422 to trusted sources to reduce exposure. Monitor for unusual subscription requests referencing invalid E2 Nodes and restart the iApp process if crashes occur.
