(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow
