A stack buffer overflow in ASUS Router firmware allows remote authenticated users to interrupt affected devices with a crafted request. The firmware writes request data past a stack-allocated buffer boundary, but ASUS has not identified the handler, field, or copy routine. Exploitation requires high-privilege network access and affects availability; no confidentiality or integrity impact is reported.
