Modern DRAM chips (DDR4 and LPDDR4 after 2015) are affected by a vulnerability in deployment of internal mitigations against RowHammer attacks known as Target Row Refresh (TRR), aka the TRRespass issue. To exploit this vulnerability, the attacker needs to create certain access patterns to trigger bit flips on affected memory modules, aka a Many-sided RowHammer attack. This means that, even when chips advertised as RowHammer-free are used, attackers may still be able to conduct privilege-escalation attacks against the kernel, conduct privilege-escalation attacks against the Sudo binary, and achieve cross-tenant virtual-machine access by corrupting RSA keys. The issue affects chips produced by SK Hynix, Micron, and Samsung. NOTE: tracking DRAM supply-chain issues is not straightforward because a single product model from a single vendor may use DRAM chips from different manufacturers.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Samsung Galaxy S10 Firmware G973FXXS3ASJA, O(8.x), P(9.0), Q(10.0) devices with Exynos chipsets. User interaction is required to exploit this vulnerability in that the target must answer a phone call. The specific flaw exists within the Call Control Setup messages. 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 in the context of the baseband processor. Was ZDI-CAN-9658.

Multiple buffer overflows in the esa_write function in /dev/seirenin the Exynos Seiren Audio driver, as used in Samsung S6 Edge, allow local users to cause a denial of service (memory corruption) via a large (1) buffer or (2) size parameter.

This vulnerability allows local attackers to disclose sensitive information on affected installations of Samsung Knox 1.2.02.39 on Samsung Galaxy S9 build G9600ZHS3ARL1 Secure Folder. An attacker must first obtain physical access to the device in order to exploit this vulnerability. The specific flaws exists within the the handling of the lock screen for Secure Folder. The issue results from the lack of proper validation that a user has correctly authenticated. An attacker can leverage this vulnerability to disclose the contents of the secure container. Was ZDI-CAN-7381.

The wemail_consumer_service (from the built-in application wemail) in Samsung Galaxy Gear series allows an unprivileged process to manipulate a user's mailbox, due to improper D-Bus security policy configurations. An arbitrary email can also be sent from the mailbox via the paired smartphone. This affects Tizen-based firmwares including Samsung Galaxy Gear series before build RE2.
