Description
In the Linux kernel, the following vulnerability has been resolved: ipmi:ssif: Clean up kthread on errors If an error occurs after the ssif kthread is created, but before the main IPMI code starts the ssif interface, the ssif kthread will not be stopped. So make sure the kthread is stopped on an error condition if it is running.
