An issue was discovered on Samsung mobile devices with any (before February 2020 for Exynos modem chipsets) software. There is a buffer overflow in baseband CP message decoding. The Samsung IDs are SVE-2019-15816 and SVE-2019-15817 (February 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.
