Background
The Kernel is a crucial component of the Linux operating system, responsible for managing system resources and facilitating communication between hardware and software. It provides essential functionalities such as process management, memory management, and device drivers. The perf arm-spe tool is a part of the Kernel's performance monitoring subsystem and is used for profiling and analyzing ARM-based systems. This vulnerability specifically affects the perf arm-spe tool when it incorrectly sets the data source for non-memory operations.
Vulnerability Detail
