Background
The Kernel is a critical component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential functionalities and services to enable the proper functioning of the system. The arm64 architecture is specifically designed for 64-bit ARM processors. This vulnerability affects the Kernel in the arm64 architecture and relates to the detection of TRBE (Translation Table Base Register) invalid prohibited states.
Vulnerability Detail
The vulnerability in the arm64 Kernel involves the detection of TRBE invalid prohibited states. TRBE is a register used for managing translation tables in the memory management unit (MMU) of the ARM processor. The issue arises when the Kernel fails to properly detect and handle invalid prohibited states of the TRBE register. This vulnerability could potentially be exploited by an attacker to manipulate memory mappings and gain unauthorized access to sensitive information or execute arbitrary code. It is important to note that the impact and attack plausibility of this vulnerability have not been proven yet.
