| CVE-2019-18990 | 1 Realtek | 8 Rtl8192er, Rtl8192er Firmware, Rtl8196d and 5 more | 2024-08-05 | 5.4 Medium |
| A partial authentication bypass vulnerability exists on Realtek RTL8812AR 1.21WW, RTL8196D 1.0.0, RTL8192ER 2.10, and RTL8881AN 1.09 devices. The vulnerability allows sending an unencrypted data frame to a WPA2-protected WLAN router where the packet is routed through the network. If successful, a response is sent back as an encrypted frame, which would allow an attacker to discern information or potentially modify data. | ||||
| CVE-2019-11867 | 1 Realtek | 1 Ndis | 2024-08-04 | 5.5 Medium |
| Realtek NDIS driver rt640x64.sys, file version 10.1.505.2015, fails to do any size checking on an input buffer from user space, which the driver assumes has a size greater than zero bytes. To exploit this vulnerability, an attacker must send an IRP with a system buffer size of 0. | ||||
| CVE-2020-27302 | 1 Realtek | 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more | 2024-08-04 | 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 | 2024-08-04 | 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-2020-26652 | 1 Realtek | 2 Rtl8812au, Rtl8812au Firmware | 2024-08-04 | 7.5 High |

| CVE-2020-25855 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-08-04 | 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-2020-25856 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-08-04 | 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-2020-25857 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-08-04 | 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-2020-25854 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-08-04 | 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 | 2024-08-04 | 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. | ||||
| CVE-2020-23539 | 1 Realtek | 2 Rtl8723de, Rtl8723de Firmware | 2024-08-04 | 7.5 High |
