been resolved:\n\nnet: openvswitch: fix possible kfree_skb of ERR_PTR\n\nAfter the patch in the \"Fixes\" tag, the allocation of the \"reply\" skb\ncan happen either before or after locking the ovs_mutex.\n\nHowever, error cleanups still follow the classical reversed order,\nassuming \"reply\" is allocated before locking: it is freed after unlocking.\n\nIf \"reply\" allocation happens after locking the mutex and it fails,\n\"reply\" is left with an ERR_PTR, and execution jumps to the correspondent\ncleanup stage which will try to free an invalid pointer.\n\nFix this by setting the pointer to NULL after having saved its error\nvalue."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
