The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

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.
