A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

mfd: core: Add locking around 'mfd_of_node_list'

Manipulating a list in the kernel isn't safe without some sort of mutual exclusion. Add a mutex any time we access / modify 'mfd_of_node_list' to prevent possible crashes.
