CVE-2022-44194Public exploitNetwork attack vector

Unauthenticated memory corruption via DNS parameters

Published Nov 22, 2022 · Updated Jul 9, 2026

Buffer overflow in NETGEAR R7000P firmware 1.3.0.8 allows remote attackers to corrupt memory via crafted DNS parameters. The public record identifies apmode_dns1_pri and apmode_dns1_sec as the triggering inputs but does not disclose the receiving routine, buffer size, or unsafe copy or write operation. Network access without credentials is sufficient, while the concrete outcome after memory corruption remains undisclosed.
