CVE-2026-37227: n/a
FlexRIC v2.0.0 contains reachable assert(0) calls in stub message handlers for whitelisted but unimplemented E2AP message types in the near-RT RIC. A remote unauthenticated attacker can send a decodable E2AP PDU of such a type (e.g., E2nodeConfigurationUpdate) to crash the near-RT RIC process (port 36421) via SIGABRT. The message passes whitelist validation but triggers an unconditional assertion in the handler.
AI Analysis
Technical Summary
The vulnerability in FlexRIC v2.0.0 involves reachable assert(0) calls in stub message handlers for specific E2AP message types that are whitelisted but not implemented. When the near-RT RIC receives such a message (e.g., E2nodeConfigurationUpdate) on port 36421, it passes whitelist validation but triggers an unconditional assertion failure, causing the process to abort. This allows a remote unauthenticated attacker to crash the near-RT RIC process, resulting in denial of service.
Potential Impact
A remote unauthenticated attacker can cause the near-RT RIC process to crash by sending a specially crafted E2AP message. This leads to a denial of service condition affecting the availability of the near-RT RIC component. There is no indication of code execution or data compromise from the provided information.
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 the near-RT RIC port 36421 to trusted sources only to reduce exposure. Monitor for unexpected process crashes and restart the service as needed.
