CVE-2026-22626Network attack vector

Authenticated service interruption via crafted messages

Published Jan 30, 2026 · Updated Jan 30, 2026

Improper parameter handling in HIKSEMI HS-AFS-S1H1 V5.10.10_Build_251126 allows remote authenticated users to interrupt service. The vendor states that a network interface accepts crafted messages without sufficient parameter validation but has not disclosed the endpoint, fields, or failed operation. High-privileged authentication is required, and the published impact is limited to abnormal device behavior affecting availability, with no reported data disclosure or modification.
