An issue was discovered on Samsung mobile devices with O(8.x) and P(9.0) (Exynos chipsets) software. A buffer overflow in the HDCP Trustlet affects secure TEEGRIS memory. The Samsung ID is SVE-2019-15283 (November 2019).
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.
