Description
In the Linux kernel, the following vulnerability has been resolved:
net: wwan: t7xx: Fix napi rx poll issue
When driver handles the napi rx polling requests, the netdev might
have been released by the dellink logic triggered by the disconnect
operation on user plane. However, in the logic of processing skb in
polling, an invalid netdev is still being used, which causes a panic.
