An issue was discovered on Samsung mobile devices with O(8.1) and P(9.0) (Exynos chipsets) software. load_kernel has a buffer overflow via untrusted data. The Samsung ID is SVE-2019-14939 (September 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.
