Background

Openvswitch is a software-based virtual switch that is commonly used in virtualized environments to enable network connectivity between virtual machines. It is a part of the Linux Kernel and provides a flexible and programmable network infrastructure. However, a vulnerability has been discovered in Openvswitch that can lead to a leak of nested actions.

Vulnerability Detail

The vulnerability in Openvswitch allows for a leak of nested actions. This means that under certain conditions, actions within actions may not be properly cleaned up, leading to a memory leak. An attacker could potentially exploit this vulnerability to exhaust system resources, resulting in a denial of service condition. The vulnerability was introduced in version v4.3 of the Linux Kernel and has been fixed in version v5.17.3.

How To Fix

No fixed version is published for this vulnerability.
