CVE-2026-43219

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: cpsw_new: Fix potential unregister of netdev that has not been registered yet<br /> <br /> If an error occurs during register_netdev() for the first MAC in<br /> cpsw_register_ports(), even though cpsw-&gt;slaves[0].ndev is set to NULL,<br /> cpsw-&gt;slaves[1].ndev would remain unchanged. This could later cause<br /> cpsw_unregister_ports() to attempt unregistering the second MAC.<br /> To address this, add a check for ndev-&gt;reg_state before calling<br /> unregister_netdev(). With this change, setting cpsw-&gt;slaves[i].ndev<br /> to NULL becomes unnecessary and can be removed accordingly.
