An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (Exynos 9810 chipsets) software. Arbitrary memory mapping exists in TEE. The Samsung ID is SVE-2019-16665 (February 2020).
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
