  "description": "In the Linux kernel, the following vulnerability has been resolved:  drbd: Fix five use after free bugs in get_initial_state  In get_initial_state, it calls notify_initial_state_done(skb,..) if cb-\u003Eargs[5]==1. If genlmsg_put() failed in notify_initial_state_done(), the skb will be freed by nlmsg_free(skb). Then get_initial_state will goto out and the freed skb will be used by return value skb-\u003Elen, which is a uaf bug.  What\u0027s worse, the same problem goes even further: skb can also be freed in the notify_*_state_change -\u003E notify_*_state calls below. Thus 4 additional uaf bugs happened.  My patch lets the problem callee functions: notify_initial_state_done and notify_*_state_change return an error code if errors happen. So that the error codes could be propagated and the uaf bugs can be avoid.  v2 reports a compilation warning. This v3 fixed this warning and built successfully in my local environment with no additional warnings. v2: https://lore.kernel.org/patchwork/patch/1435218/",
