CVE-2026-98351

In the Linux kernel, the following vulnerability has been resolved: wifi: virt_wifi: free skb when disconnected When the simulated link is disconnected, virt_wifi_start_xmit() returns NET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this return value as consumed, so every packet sent while disconnected leaks its skb. Free the skb before returning the drop status.
