Background
The Kernel is a critical component of the Linux operating system that manages communication between hardware and software. It provides essential functions and services to ensure the proper functioning of the system. The mpt3sas driver is responsible for managing SCSI devices connected to the system. It allows for communication and control of SAS (Serial Attached SCSI) devices. However, a vulnerability has been discovered in the mpt3sas driver that can lead to a kernel panic during a drive powercycle test.
Vulnerability Detail
The vulnerability in the mpt3sas driver occurs during a drive powercycle test. When this test is performed, it triggers a kernel panic, causing the system to crash. This vulnerability can be exploited by an attacker with local access to the system. By executing the powercycle test, they can cause a denial of service (DoS) condition, disrupting the normal operation of the system. The vulnerability was introduced in version v3.8 of the Linux Kernel and has been fixed in version v5.4.163.
How To Fix
