CVE-2022-44190Network attack vector

Remote compromise via enable_band_steering overflow

Published Nov 22, 2022 · Updated Apr 29, 2025

Buffer overflow in Netgear R7000P firmware 1.3.1.64 allows remote attackers to compromise confidentiality, integrity, and availability. The network management handler processes the enable_band_steering parameter without sufficient bounds enforcement, allowing oversized input to overwrite memory. The published CVSS vector specifies no authentication or user interaction, so a network-reachable device can be affected remotely; exact code-execution behavior is not disclosed.
