Samsung » Galaxy S6 Firmware : Security Vulnerabilities, CVEs,

Buffer overflow in dhd_bus_flow_ring_create_response in drivers/net/wireless/bcmdhd4358/dhd_pcie.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allow an attacker (who has obtained code execution on the Wi-Fi) chip to cause the device driver to perform invalid memory accesses. The Samsung ID is SVE-2018-11785.

Buffer overflow in dhd_bus_flow_ring_flush_response in drivers/net/wireless/bcmdhd4358/dhd_pcie.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 allow an attacker (who has obtained code execution on the Wi-Fi chip) to cause the device driver to perform invalid memory accesses. The Samsung ID is SVE-2018-11785.

Buffer overflow in dhd_bus_flow_ring_delete_response in drivers/net/wireless/bcmdhd4358/dhd_pcie.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allow an attacker (who has obtained code execution on the Wi-Fi chip) to cause the device driver to perform invalid memory accesses. The Samsung ID is SVE-2018-11785.

A NULL pointer dereference in dhd_prot_txdata_write_flush in drivers/net/wireless/bcmdhd4358/dhd_msgbuf.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allows an attacker (who has obtained code execution on the Wi-Fi chip) to cause the device to reboot. The Samsung ID is SVE-2018-11783.

Out-of-bounds array access in dhd_rx_frame in drivers/net/wireless/bcmdhd4358/dhd_linux.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allows an attacker (who has obtained code execution on the Wi-Fi chip) to cause invalid accesses to operating system memory due to improper validation of the network interface index provided by the Wi-Fi chip's firmware.

Buffer overflow in prot_get_ring_space in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allows an attacker (who has obtained code execution on the Wi-Fi chip) to overwrite kernel memory due to improper validation of the ring buffer read pointer. The Samsung ID is SVE-2018-12029.

Samsung SM-G920F build G920FXXU2COH2 (Galaxy S6), SM-N9005 build N9005XXUGBOK6 (Galaxy Note 3), GT-I9192 build I9192XXUBNB1 (Galaxy S4 mini), GT-I9195 build I9195XXUCOL1 (Galaxy S4 mini LTE), and GT-I9505 build I9505XXUHOJ2 (Galaxy S4) devices do not block AT+USBDEBUG and AT+WIFIVALUE, which allows attackers to modify Android settings by leveraging AT access, aka SVE-2016-5301.

Samsung SM-G920F build G920FXXU2COH2 (Galaxy S6), SM-N9005 build N9005XXUGBOK6 (Galaxy Note 3), GT-I9192 build I9192XXUBNB1 (Galaxy S4 mini), GT-I9195 build I9195XXUCOL1 (Galaxy S4 mini LTE), and GT-I9505 build I9505XXUHOJ2 (Galaxy S4) devices allow attackers to send AT commands by plugging the device into a Linux host, aka SVE-2016-5301.

Samsung SM-G920F build G920FXXU2COH2 (Galaxy S6), SM-N9005 build N9005XXUGBOK6 (Galaxy Note 3), GT-I9192 build I9192XXUBNB1 (Galaxy S4 mini), GT-I9195 build I9195XXUCOL1 (Galaxy S4 mini LTE), and GT-I9505 build I9505XXUHOJ2 (Galaxy S4) devices have unintended availability of the modem in USB configuration number 2 within the secure lockscreen state, allowing an attacker to make phone calls, send text messages, or issue commands, aka SVE-2016-5301.

secfilter in the Samsung kernel for Android on SM-N9005 build N9005XXUGBOB6 (Note 3) and SM-G920F build G920FXXU2COH2 (Galaxy S6) devices allows attackers to bypass URL filtering by inserting an "exceptional URL" in the query string, as demonstrated by the http://should-have-been-filtered.example.com/?http://google.com URL.

Samsung SecEmailSync on SM-G920F build G920FXXU2COH2 (Galaxy S6) devices has SQL injection, aka SVE-2015-5081.

Samsung SecEmailSync on SM-G920F build G920FXXU2COH2 (Galaxy S6) devices allows attackers to read sent e-mail messages, aka SVE-2015-5081.

The getURL function in drivers/secfilter/urlparser.c in secfilter in the Samsung kernel for Android on SM-N9005 build N9005XXUGBOB6 (Note 3) and SM-G920F build G920FXXU2COH2 (Galaxy S6) devices allows attackers to trigger a NULL pointer dereference via a "GET HTTP/1.1" request, aka SVE-2016-5036.
