Description OSIDB Bzimport 2026-10-06 09:25:41 UTC 
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.
