Preface: Use-after-free (UAF) vulnerabilities are a class of software flaws that involve using a memory resident object after it has been freed. UAF vulnerabilities most commonly occur when a C++ object that was allocated on the heap is accessed after it is deleted, but stack-allocated objects can also be used after a free. Background: The…

Preface: Android Auto is a platform running on the user’s phone, projecting the Android Auto user experience to a compatible in-vehicle infotainment system over a USB connection. Android Auto supports apps designed for in-vehicle use. Background: The Android for Cars App Library lets you bring your navigation, point of interest (POI), and internet of things…

Preface: The Cortex-M3 processor is specifically developed for high-performance, low-cost platforms for a broad range of devices including microcontrollers, automotive body systems, industrial control systems and wireless networking and sensors. Background: SCP Firmware provides a software reference implementation for the System Control Processor (SCP) and Manageability Control Processor (MCP) components found in several Arm Compute…

Preface: The Cortex-M stands for the Microcontroller which is used in most of our daily life applications also starting from the automation to DSP applications, sensors, smart displays, IoT applications ,etc. Background: In April of 2024, Arm Limited published a Cortex-M Security Extensions (CMSE) Security Bulletin that identifies a potential software security issue in code…

Preface: What is an MF4/MDF4 file? Measurement Data Format version 4 (MDF 4) is a standard file format by ASAM used by the automotive industry for storing measurement data in binary file format. It records CAN, CAN FD, LIN bus data, sensor data from an engine control unit (ECU), offering interoperability across many CAN tools. Background:…

Preface: A stack is not flexible, the memory size allotted cannot be changed whereas a heap is flexible, and the allotted memory can be altered. Background: Escargot is a memory optimized JavaScript engine for mid-range devices such as mobile phone, tablet and TV. C++. •. GNU Lesser General Public License v2.1. Memory Efficiency: The engine…

Preface: In computer programming, transient is a property of any element in the system that is temporary. The term applies to transient applications. Background: Within frequency, In-band discovery is used for communication between 6 GHz devices. There are three in-band discovery methods: Fast Initial Link Setup (FILS) and Unsolicited Probe Response (UPR) frames are passive…

Preface: Use after free errors sometimes have no effect and other times cause a program to crash. While it is technically feasible for the freed memory to be re-allocated and for an attacker to use this reallocation to launch a buffer overflow attack. Background: When the GPU returns ownership of the buffer to the CPU,…
