CVE-2026-37226: n/a
FlexRIC v2.0.0 crashes when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST referencing a non-existent E2 Node. The lookup function returns NULL, which is enforced by assert() in Debug builds (SIGABRT) and dereferenced in Release builds (SIGSEGV). A remote unauthenticated attacker can crash the iApp process (port 36422) by sending a subscription request with an arbitrary global_e2_node_id.
AI Analysis
Technical Summary
The vulnerability in FlexRIC v2.0.0 involves improper handling of subscription requests referencing non-existent E2 Nodes. Specifically, the lookup function returns NULL, which triggers 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 E42_RIC_SUBSCRIPTION_REQUEST with an arbitrary global_e2_node_id to port 36422, resulting in denial of service.
Potential Impact
This vulnerability allows remote unauthenticated attackers to cause a denial of service by crashing the iApp process on FlexRIC v2.0.0. There is no indication of confidentiality or integrity impact. The CVSS score of 7.5 reflects a high severity due to the ease of remote exploitation and complete service disruption.
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 apply any vendor-provided mitigations once released.
