In the Linux kernel, the following vulnerability has been resolved:

forcedeth: fix UAF of txrx_stats in nv_remove

nv_remove() frees the per-CPU txrx_stats before unregister_netdev().

Until unregister completes, ndo_get_stats64, the NAPI/xmit data path,

and nv_close()/drain may still access txrx_stats, leading to a

use-after-free.

Free the stats only after unregister_netdev(). (NVD)
