An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (Broadcom Bluetooth chipsets) software. The Bluetooth UART driver has a buffer overflow. The Samsung ID is SVE-2020-18731 (January 2021).
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.
