Description
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 bcm_op's is already implemented with rcu handling this patch adds the missing rcu_read_lock() and makes sure the list entries are properly removed under rcu protection.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is in the Linux kernel's CAN subsystem for Broadcom (bcm). It occurs because the procfs content generation for a bcm_op object that is being removed lacks proper RCU (Read-Copy-Update) read protection. This can cause the procfs output to show unreliable data due to a use-after-free (UAF) condition. The issue is fixed by adding the missing rcu_read_lock() to ensure safe access and proper removal of list entries under RCU protection.


How can this vulnerability impact me? :

The vulnerability can cause the procfs interface to display unreliable or stale data due to a use-after-free condition when accessing bcm_op objects being removed. This could potentially lead to system instability or incorrect information being presented to users or monitoring tools that rely on procfs data.
