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 functionality for the proper functioning of the system. One of its features is dm stats, which is used for monitoring and collecting statistics related to device mapper (dm) subsystem. The dm stats feature allows users to gather information about the performance and usage of dm devices.
However, a vulnerability has been discovered in the dm stats feature, which could potentially lead to security issues.
Vulnerability Detail
The vulnerability in dm stats arises from a missing cond_resched call when looping over entries. This omission can result in a denial-of-service (DoS) scenario or other security implications. Attackers may exploit this vulnerability to cause system crashes or disrupt the normal operation of the dm stats feature. The impact and attack plausibility of this vulnerability have not been proven yet.
This vulnerability has been addressed in the Linux Kernel version v4.14.282 by commit 1dbcb821c63d09dc4a641bf99bb05f238610717f.
