Description
A flaw was found in the Linux kernel's Intelligent Platform Management Interface (IPMI) driver. This vulnerability allows a malfunctioning Baseboard Management Controller (BMC) to cause the IPMI driver to continuously fetch events and messages, or become stuck if the attention bit remains active. This can lead to the driver becoming unresponsive, potentially resulting in a denial of service for the system.
