An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), Q(10.0), and R(11.0) (Exynos chipsets) software. The Mali GPU driver allows out-of-bounds access and a device reset. The Samsung ID is SVE-2020-19174 (January 2021).

An issue was discovered in the fingerprint scanner on Samsung Note20 mobile devices with Q(10.0) software. When a screen protector is used, the required image compensation is not present. Consequently, inversion can occur during fingerprint enrollment, and a high False Recognition Rate (FRR) can occur. The Samsung ID is SVE-2020-19216 (January 2021).

An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (Broadcom Bluetooth chipsets) software. The Bluetooth UART driver has a buffer overflow. The Samsung ID is SVE-2020-18731 (January 2021).
