Title
net: openvswitch: fix skb leak on flow key update failure during ct
Summary
In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix skb leak on flow key update failure during ct ovs_ct_execute() always steals or frees the skb on failure while ovs_flow_key_update() does not. So, if it fails and we return right away, the skb ends up leaked. Fix that by breaking instead and letting the common error handling code at the bottom of the loop to free the skb properly. This is a very unlikely scenario as it requires the packet to become unparseable by applying a set of actions on a previously parseable skb, but should be fixed nevertheless. Reported by Sashiko.

So, if it fails and we return right\naway, the skb ends up leaked.\n\nFix that by breaking instead and letting the common error handling\ncode at the bottom of the loop to free the skb properly.\n\nThis is a very unlikely scenario as it requires the packet to become\nunparseable by applying a set of actions on a previously parseable skb,\nbut should be fixed nevertheless.\n\nReported by Sashiko."
