CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's Open vSwitch component, specifically during the flow key update process, where a failure can lead to a memory leak of socket buffers (skbs). Although the likelihood of exploitation is low, as it requires specific conditions to render packets unparseable, it is important for organizations using Linux systems with Open vSwitch to prioritize this fix to maintain optimal memory management and system stability. System administrators and security teams should ensure that their environments are updated to mitigate this potential risk.
Original NVD Description
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.
