An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (Exynos chipsets) software. The secure bootloade has a buffer overflow of the USB buffer, leading to arbitrary code execution. The Samsung ID is SVE-2019-15872 (January 2020).
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
