VAR-202102-0234

Vulnerability from variot - Updated: 2023-12-18 14:00

The function ClientEAPOLKeyRecvd() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. Realtek RTL8195A Wi-Fi The module contains a vulnerability related to out-of-bounds writing.Denial of service (DoS) It may be put into a state. Realtek RTL8195A is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek).

Realtek RTL8195A versions prior to 2.08 have a buffer overflow vulnerability
