What is CVE-2026-37222?
CVE-2026-37222 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 uses hardcoded assertions to validate Information Element (IE) counts in decoded E2AP messages. A remote unauthenticated attacker can send a valid E2AP PDU containing an unexpected number of IEs (e.g., an E2setupRequest with extra optional fields) to crash the near-RT RIC (port 36421) or iApp (port 36422) via SIGABRT. The code asserts exact IE counts rather than validating against protocol-specified ranges.
Weakness: CWE-617
