In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: fix possible kfree_skb of ERR_PTR
After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovs_mutex.
However, error cleanups still follow the classical reversed order, assuming "reply" is allocated before locking: it is freed after unlocking.
If "reply" allocation happens after locking the mutex and it fails, "reply" is left with an ERR_PTR, and execution jumps to the correspondent cleanup stage which will try to free an invalid pointer.
Fix this by setting the pointer to NULL after having saved its error value.
