An issue was discovered on Samsung mobile devices with software through 2015-11-12, affecting the Galaxy S6/S6 Edge, Galaxy S6 Edge+, and Galaxy Note5 with the Shannon333 chipset. There is a stack-based buffer overflow in the baseband process that is exploitable for remote code execution via a fake base station. The Samsung ID is SVE-2015-5123 (December 2015).
An issue was discovered on Samsung mobile devices with software through 2016-04-05 (incorporating the Samsung Professional Audio SDK). The Jack audio service doesn't implement access control for shared memory, leading to arbitrary code execution or privilege escalation. The Samsung ID is SVE-2016-5953 (July 2016).
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.
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.
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.
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.
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_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.
LibQJpeg in the Samsung Galaxy S6 before the October 2015 MR allows remote attackers to cause a denial of service (memory corruption and SIGSEGV) via a crafted image file.
