CVE-2026-110491 Kiloview CVE debrief
CVE-2026-110491 Kiloview E3 NDI Encoder NULL Pointer Dereference. The vulnerability affects the ONVIF service, causing it to become unresponsive when receiving malformed or incomplete requests. This results in the service stopping accepting new connections while the device continues operating normally. The service recovers automatically after a period. Unaffected parties can trigger this repeatedly with network access to the device. Defenders of ICS systems, particularly those using Kiloview E3 NDI Encoders, should assess exposure and apply necessary mitigations.
