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

The CVE record on cve.org NVD's entry
The CVE record is authoritative. Products marked “from the name” were identified from the CNA's free-text names, not a CPE, and are matched less certainly. This product uses the NVD API but is not endorsed or certified by the NVD.
