CVE-2026-74464
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() alway
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.
