I don't see the v1 on netdev@, nor a link to it in the change log
so I may be missing the context, but the commit message is a bit
sparse.

The stable and Fixes tags indicate this is a fix. But the commit
message reads like currently no such crash is observed, quote:

                          which could lead to a dangling pointer.
                                ^^^^^
                                     ?

Could someone clarify?
