Description

A flaw was found in the Linux kernel's openvswitch vport component. This vulnerability arises during the release of tunnel ports, where a self-deadlock can occur. This prevents the vport from being properly freed and its references released, leading to a system deadlock during device removal. Such a deadlock can negatively impact system stability and performance, potentially resulting in a Denial of Service (DoS).
