kernel: Linux kernel: Denial of Service in intel-xway PHY driver due to OF node reference count leakage
In the Linux kernel, the following vulnerability has been resolved:
net: phy: intel-xway: fix OF node refcount leakage
Automated review spotted am OF node reference count leakage when
checking if the 'leds' child node exists.
Call of_put_node() to correctly maintain the refcount.
A flaw was found in the Linux kernel's intel-xway PHY (Physical Layer) driver. This vulnerability involves an improper management of Open Firmware (OF) node reference counts. A local attacker could exploit this by repeatedly triggering a specific condition, leading to resource exhaustion and ultimately a denial of service (DoS) on the system.
