CVE-2026-110491 · Severity: high · CVSS 7.5 · Published 2026-10-22

The Kiloview E3 NDI Encoder is a video encoding device used in broadcast and streaming operations. An unauthenticated attacker with network access can crash the ONVIF service by sending malformed requests, making the device unable to accept new connections until it automatically recovers. While the rest of the device continues operating and recovery is automatic, repeated attacks could disrupt video encoding and management operations.
