Background
The Kernel is a critical component of the Linux operating system that provides core functionality and interfaces with hardware devices. It manages system resources, facilitates communication between software and hardware, and ensures the stability and security of the system. The ipmi module in the Kernel is responsible for handling Intelligent Platform Management Interface (IPMI) operations, which allow remote management and monitoring of computer systems. IPMI is commonly used in server environments to perform tasks such as power control, sensor monitoring, and event logging. However, a vulnerability has been discovered in the ipmi module that affects its initialization when workqueue allocation fails.
Vulnerability Detail
The vulnerability in the ipmi module occurs during initialization when the allocation of a workqueue fails. A workqueue is a mechanism in the Kernel that allows for the execution of tasks in a separate context, typically used for asynchronous processing. When the workqueue allocation fails, the ipmi module fails to properly initialize, potentially leading to undefined behavior or system instability. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in Linux Kernel version v4.19.223 by commit eb84855d3e8799b67cdbadc7a5c53997cbfc3580. The vulnerability was introduced in version v4.19.220 by commit 36fbc46a792969650a44702ddd2143fe722e4d00.
