Linux Kernel OF Node Reference Count Leakage Vulnerability in Intel XWAY PHY Driver

A reference count leakage vulnerability has been identified in the Linux kernel's Intel XWAY PHY driver. This issue arises when the driver checks for the existence of the 'leds' child node, leading to an improper management of the reference count for the device tree node. The vulnerability affects the stable versions of the Linux kernel.

Impact

The vulnerability could lead to a reference count leakage, which may cause improper memory management and potentially allow for use-after-free conditions.

Remediation

Users can apply the patch available in the Linux kernel stable tree to address this vulnerability.
