In the Linux kernel, the following vulnerability has been resolved:
can: bcm: add missing rcu read protection for procfs content
When the procfs content is generated for a bcm_op which is in the process to be removed the procfs output might show unreliable data (UAF).
As the removal of bcmop's is already implemented with rcu handling this patch adds the missing rcuread_lock() and makes sure the list entries are properly removed under rcu protection.
