Overview

About vulnerability

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. A flaw was found in the Linux kernel’s multi-function device (mfd) core module. The mfd_of_node_list lacked proper locking mechanisms, allowing for unsafe manipulation of the list. This concurrency issue could lead to system crashes, resulting in a Denial of Service (DoS).
