Open vSwitch provides standard network bridging functions and support for
the OpenFlow protocol for remote per-flow control of traffic.

  • openvswitch: limitation in the OVS packet parsing in userspace leads to DoS (CVE-2020-35498)

  • lldp/openvswitch: denial of service via externally triggered memory leak (CVE-2020-27827)
