Linux Kernel Refcount Leak Vulnerability in Regulator PFUZE100

Vulnerability

A refcount leak vulnerability has been identified in the Linux kernel's handling of the PFUZE100 regulator. The issue arises in the function responsible for parsing regulator nodes from device tree overlays, where a reference count is improperly managed. This leak can lead to memory management issues, as the reference count is not decremented when the node is no longer needed.

Impact

Exploitation of this vulnerability can cause a refcount leak, leading to potential memory management issues within the kernel.
