    CVE-2020-25857 (GCVE-0-2020-25857)

    Vulnerability from nvd – Published: 2021-02-03 16:48 – Updated: 2024-08-04 15:49
    VLAI
    Summary
    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.
    Severity
    No CVSS data available.

    CVE-2020-25856 (GCVE-0-2020-25856)

    Vulnerability from nvd – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
    VLAI
    Summary
    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.
    Severity
    No CVSS data available.

    CVE-2020-25853 (GCVE-0-2020-25853)

    Vulnerability from nvd – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
    VLAI
    Summary
    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.
    Severity
    No CVSS data available.

    VLAI
    Summary
    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-2020-25853 (GCVE-0-2020-25853)

    Vulnerability from cvelistv5 – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
    VLAI
    Summary
    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.
    Severity
    No CVSS data available.

    CVE-2020-25855 (GCVE-0-2020-25855)

    Vulnerability from cvelistv5 – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
    VLAI
    Summary
    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.
