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. One of the features supported by the Kernel is Non-Volatile Dual In-line Memory Module (NVDIMM), which allows persistent memory to be used as block devices. However, a vulnerability has been discovered in the Kernel that can lead to firmware activation deadlock scenarios in NVDIMM.
Vulnerability Detail
The vulnerability in the Kernel affects the firmware activation process of NVDIMM. Under certain circumstances, a deadlock can occur during the activation, causing the system to become unresponsive. This vulnerability can be exploited by an attacker to disrupt the normal operation of the system or potentially execute arbitrary code. The issue was introduced in Kernel version v5.9 and has been fixed in version v5.15.46.
