Until an official fix is available, consider implementing network-level protections such as filtering or rate limiting traffic to port 36422 to reduce exposure. Monitor for unusual crashes of the iApp process and restart services as needed.

Description

CVE-2026-37225 is a vulnerability in FlexRIC v2.0.0 where the iApp process crashes when it receives an E42_RIC_SUBSCRIPTION_REQUEST containing an empty ricEventTriggerDefinition field. This occurs due to a mismatch in validation between the E42 layer decoder, which accepts the empty field as valid, and the E2AP encoder, which requires it to be non-empty. A remote unauthenticated attacker can exploit this to cause a denial of service by crashing the iApp process via SIGABRT. The vulnerability has a high severity with a CVSS score of 7.5 and is categorized under CWE-617 (Reachable Assertion). No patch or official remediation guidance is currently available.
