CVE-2022-34326 1 Realtek 2 Rtl8195am, Rtl8195am Firmware 2025-05-21 7.5 High
In ambiot amb1_sdk (aka SDK for Ameba1) before 2022-06-20 on Realtek RTL8195AM devices before 284241d70308ff2519e40afd7b284ba892c730a3, the timer task and RX task would be locked when there are frequent and continuous Wi-Fi connection (with four-way handshake) failures in Soft AP mode.
CVE-2021-43573 1 Realtek 2 Rtl8195am, Rtl8195am Firmware 2024-11-21 9.8 Critical
A buffer overflow was discovered on Realtek RTL8195AM devices before 2.0.10. It exists in the client code when processing a malformed IE length of HT capability information in the Beacon and Association response frame.
CVE-2021-39306 1 Realtek 2 Rtl8195am, Rtl8195am Firmware 2024-11-21 9.8 Critical
A stack buffer overflow was discovered on Realtek RTL8195AM device before 2.0.10, it exists in the client code when an attacker sends a big size Authentication challenge text in WEP security.
CVE-2020-9395 1 Realtek 8 Rtl8195am, Rtl8195am Firmware, Rtl8710af and 5 more 2024-11-21 8.0 High
An issue was discovered on Realtek RTL8195AM, RTL8711AM, RTL8711AF, and RTL8710AF devices before 2.0.6. A stack-based buffer overflow exists in the client code that takes care of WPA2's 4-way-handshake via a malformed EAPOL-Key packet with a long keydata buffer.
CVE-2020-27302 1 Realtek 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more 2024-11-21 8.0 High
A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "memcpy" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake.
CVE-2020-27301 1 Realtek 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more 2024-11-21 8.0 High
A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "AES_UnWRAP" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake.
CVE-2020-25857 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2024-11-21 7.5 High
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.
CVE-2020-25856 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2024-11-21 8.1 High
The function DecWPA2KeyData() 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 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.
CVE-2020-25855 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2024-11-21 8.1 High
The 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.
CVE-2020-25854 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2024-11-21 8.1 High
The function DecWPA2KeyData() 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 internal function, rt_arc4_crypt_veneer() or _AES_UnWRAP_veneer(), 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.
CVE-2020-25853 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2024-11-21 7.5 High
The function CheckMic() 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 internal function, _rt_md5_hmac_veneer() or _rt_hmac_sha1_veneer(), resulting in a stack buffer over-read 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.
