Authenticated memory corruption via undisclosed buffer overflow
Published Dec 26, 2021 · Updated Aug 4, 2024
Buffer overflow in NETGEAR router, extender, and WiFi system firmware allows remote authenticated users to cause an unspecified impact. NETGEAR has not published the affected component, input vector, buffer operation, or resulting behavior beyond identifying a post-authentication buffer overflow. Public records conflict on the access gate: the narrative requires authentication, while the published assessment treats the flaw as unauthenticated and adjacent-network reachable.
