An issue was discovered on Samsung mobile devices with N(7.x) and O(8.0) (Galaxy S9+, Galaxy S9, Galaxy S8+, Galaxy S8, Note 8). There is access to Clipboard content in the locked state via the Edge panel. The Samsung ID is SVE-2017-10748 (May 2018).

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8 G950FXXU1AQL5. User interaction is required to exploit this vulnerability in that the target must have their cellular radios enabled. The specific flaw exists within the handling of IPCP headers. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the baseband processor. Was ZDI-CAN-5368.

On Samsung mobile devices with O(8.0) and P(9.0) software and an Exynos 8895 chipset, RKP (aka the Samsung Hypervisor EL2 implementation) allows arbitrary memory write operations. The Samsung ID is SVE-2019-16265.

Bluetooth. An issue existed with the use of a PRNG with low entropy. This issue was addressed with improved state management.
