Authenticated device service interruption
Published Aug 11, 2026 · Updated Aug 11, 2026
Stack-based buffer overflow in NETGEAR MR70, MR90, MS70, MS90, and RAX-series firmware allows remote authenticated users to interrupt service. NETGEAR has not disclosed the affected component, input field, or memory-copy operation that overflows the stack. Exploitation requires an administrator on the adjacent network and temporarily makes the device unavailable, with no reported confidentiality or integrity impact.
