·Updated
In the Linux kernel, the following vulnerability has been resolved:
ipmi: Remove all sysfs files on registration failure
ipmiaddsmi() creates the nrusers and nrmsgs files before trying to create the maintenancemode file. If that last creation fails, the error path removes only nrusers before dropping the final reference to the interface.
Remove nrmsgs as well so no sysfs attribute embedded in the freed interface remains registered.
