Description Avinash Hanwate 2022-12-21 04:13:07 UTC

Multiple versions of Open vSwitch are vulnerable to crafted LLDP packets causing a denial of service. Triggering the vulnerabilities requires LLDP processing to be enabled for a specific port.  Open vSwitch versions prior to 2.4.0 are not vulnerable.
