"Kernel address space layout random iz ation (KASLR) is one of the security features introduced in Android. How does KASLR work?”

KASLR (Kernel Address Space Layout Randomization) is a security feature that randomizes the memory locations where the kernel code is loaded each time the system boots. This makes it significantly harder for attackers to predict the addresses of kernel functions and data structures. By obscuring these locations, KASLR mitigates code reuse attacks, such as Return-Oriented Programming (ROP), which rely on knowing the exact memory addresses of existing code snippets to execute malicious operations. Without predictable addresses, attackers cannot reliably craft exploits, especially for remote attacks. The incorrect options describe other security concepts or misrepresent KASLR's function. KASLR does not separate the HAL (Hardware Abstraction Layer) or randomize application load locations (that's ASLR for user-space applications), nor does it randomize passcode hashes.
