CVE-2026-37225
HIGHFlexRIC 2.0.0 - Unauthenticated Denial of Service via Empty ricEventTriggerDefinition Field
Title source: llmDescription
FlexRIC v2.0.0 crashes when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST with an empty ricEventTriggerDefinition field. The E42 layer decoder accepts this as valid, but the E2AP encoder asserts a non-empty constraint when forwarding the request. A remote unauthenticated attacker can crash the iApp process (port 36422) via SIGABRT by exploiting this cross-layer validation mismatch.
