- Details
-
In the Linux kernel, the following vulnerability has been resolved:
idpf: check error for register_netdev() on init
Current init logic ignores the error code from register_netdev(), which will cause WARN_ON() on attempt to unregister it, if there was one, and there is no info for the user that the creation of the netdev failed.
WARNING: CPU: 89 PID: 6902 at net/core/dev.c:11512 unregister_netdevice_many_notify+0x211/0x1a10 ...

Introduce an error check and log the vport number and error code. On removal make sure to check VPORT_REG_NETDEV flag prior to calling unregister and free on the netdev.
Add local variables for idx, vport_config and netdev for readability.
