What is CVE-2026-37225?
CVE-2026-37225 is a high-severity denial of service vulnerability in n/a, published on 1 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-617
