An issue was discovered on Samsung mobile devices with O(8.X), P(9.0), and Q(10.0) (Exynos chipsets) software. Attackers can bypass the Secure Bootloader protection mechanism via a heap-based buffer overflow to execute arbitrary code. The Samsung ID is SVE-2020-16712 (May 2020).

An issue was discovered on Samsung mobile devices with Q(10.0) software. Attackers can bypass the locked-state protection mechanism and access clipboard content via USSD. The Samsung ID is SVE-2019-16556 (May 2020).

There is a buffer overwrite vulnerability in the Quram qmg library of Samsung's Android OS versions O(8.x), P(9.0) and Q(10.0). An unauthenticated, unauthorized attacker sending a specially crafted MMS to a vulnerable phone can trigger a heap-based buffer overflow in the Quram image codec leading to an arbitrary remote code execution (RCE) without any user interaction. The Samsung ID is SVE-2020-16747.
