Jul 30 RESCORED — CVE-2025-38003 (Linux). CVSS 7.8 → 5.5 (NVD).
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.
