Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
forcedeth: fix UAF of txrx_stats in nv_remove<br />
<br />
nv_remove() frees the per-CPU txrx_stats before unregister_netdev().<br />
Until unregister completes, ndo_get_stats64, the NAPI/xmit data path,<br />
and nv_close()/drain may still access txrx_stats, leading to a<br />
use-after-free.<br />
<br />
Free the stats only after unregister_netdev().
