In the Linux kernel, the following vulnerability has been resolved: net:
gtp: Fix Use-After-Free in gtp_dellink Since call_rcu, which is called in
the hlist_for_each_entry_rcu traversal of gtp_dellink, is not part of the
RCU read critical section, it is possible that the RCU grace period will
pass during the traversal and the key will be free. To prevent this, it
should be changed to hlist_for_each_entry_safe.
