CVE-2026-64228

In the Linux kernel, the following vulnerability has been resolved: net: ethtool: phy: avoid NULL deref when PHY driver is unbound phydev->drv can become NULL while the phy_device is still attached to its net_device, namely after the PHY driver is unbound via sysfs: echo <mdio_id> > /sys/bus/mdio_bus/drivers/<phy_drv>/unbind phy_remove() clears phydev->drv but doesn't call phy_detach(), so the phy_device stays in the link topology xarray and ethnl_req_get_phydev() still hands it back.
