VAR-202102-0232
Vulnerability from variot - Updated: 2023-12-18 12:27The function AES_UnWRAP() 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 a memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or 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 needs to know the network's PSK in order to exploit this. Realtek RTL8195AM is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek). Realtek RTL8195A Wi-Fi Module prior to versions 2.08 has a buffer error vulnerability
