Background
The Kernel is a critical component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functionalities such as process management, memory management, and device drivers. The proc_dou8vec_minmax() function is a part of the sysctl subsystem in the Kernel, which allows users to configure and monitor various system parameters. However, this function is vulnerable to data races, which can lead to unpredictable behavior and potential security issues.
Vulnerability Detail
The data races in proc_dou8vec_minmax() can occur when multiple threads or processes access and modify the same data simultaneously without proper synchronization. This can result in inconsistent or corrupted data, leading to various problems such as crashes, incorrect system behavior, or even security vulnerabilities. Attackers may exploit these data races to manipulate system parameters, gain unauthorized access, or cause denial-of-service conditions. The vulnerability was introduced in Linux Kernel version 5.13 and has been fixed in version 5.15.56.
