Multiple buffer overflows in the esa_write function in /dev/seirenin the Exynos Seiren Audio driver, as used in Samsung S6 Edge, allow local users to cause a denial of service (memory corruption) via a large (1) buffer or (2) size parameter.

Xiaomi Mi 5s Plus devices allow attackers to trigger touchscreen anomalies via a radio signal between 198 kHz and 203 kHz, as demonstrated by a transmitter and antenna hidden just beneath the surface of a coffee-shop table, aka Ghost Touch.

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.

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.

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.

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.

The DCMProvider service in Samsung LibQjpeg on a Samsung SM-G925V device running build number LRX22G.G925VVRU1AOE2 allows remote attackers to cause a denial of service (segmentation fault and process crash) and execute arbitrary code via a crafted JPG.

Directory traversal vulnerability in the WifiHs20UtilityService on the Samsung S6 Edge LRX22G.G925VVRU1AOE2 allows remote attackers to overwrite or create arbitrary files as the system-level user via a .. (dot dot) in the name of a file, compressed into a zipped file named cred.zip, and downloaded to /sdcard/Download.
