Linux Kernel Dpaa2 Ptp Refcount Leak Vulnerability

A refcount leak vulnerability has been addressed in the Linux kernel's dpaa2-ptp component. The issue arose because a node pointer returned by of_find_compatible_node() had an incremented refcount, which was not properly decremented, leading to the leak. The vulnerability has been fixed by adding a call to of_node_put() to correct the refcount management.

Impact

Exploitation of this vulnerability could lead to a refcount leak, potentially causing memory management issues.
