CVE-2025-40239

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: phy: micrel: always set shared-&gt;phydev for LAN8814<br /> <br /> Currently, during the LAN8814 PTP probe shared-&gt;phydev is only set if PTP<br /> clock gets actually set, otherwise the function will return before setting<br /> it.<br /> <br /> This is an issue as shared-&gt;phydev is unconditionally being used when IRQ<br /> is being handled, especially in lan8814_gpio_process_cap and since it was<br /> not set it will cause a NULL pointer exception and crash the kernel.<br /> <br /> So, simply always set shared-&gt;phydev to avoid the NULL pointer exception.
