CVE-2026-96274: Baicells Nova 430h Enodeb Model PBS3101SH

High severity, CVSS 7.4. EPSS: 0.2% chance of exploitation in the next 30 days.

In Baicells Nova 430H, an unauthenticated device within radio range can send a malformed uplink message during connection setup that contains an invalid NAS payload. Because the eNodeB does not properly validate this payload, it forwards the message to the core network, which can trigger a shutdown of the signaling association for the cell. This results in a temporary service disruption until the eNodeB and core network re-establish connectivity.
