CVE-2026-74548
forcedeth: fix UAF of txrx_stats in nv_remove
Description
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().
