disconnected, virt_wifi_start_xmit() returns\nNET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this\nreturn value as consumed, so every packet sent while disconnected leaks its\nskb.\n\nFree the skb before returning the drop status.","state":0,"publishedAt":"2026-10-06T08:46:39.335+00:00","modifiedAt":"2026-10-19T09:18:02.098+00:00","affected":[{"ecosystem":"Vendor
