CVE-2022-49351 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: altera: Fix refcount leak in altera_tse_mdio_create Every iteration of for_each_child_of_node() decrements the reference count of the previous node. When break from a for_each_child_of_node() loop, we need to explicitly call of_node_put() on the child node when not need anymore. Add missing of_node_put() to avoid refcount leak.
A refcount leak vulnerability has been identified in the Linux kernel's handling of Altera TSE MDIO creation. The issue arises because each iteration of the 'for_each_child_of_node()' function decreases the reference count of the previous node. When exiting the loop, the child node must be explicitly released using 'of_node_put()' to prevent a reference count leak. The vulnerability has been addressed by adding the missing 'of_node_put()' call.
