Detail

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.
