NVD Description

Note: Versions mentioned in the description apply only to the upstream openvswitch package and not the openvswitch package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The TSS (Tuple Space Search) algorithm in Open vSwitch 2.x through 2.17.2 and 3.0.0 allows remote attackers to cause a denial of service (delays of legitimate traffic) via crafted packet data that requires excessive evaluation time within the packet classification algorithm for the MegaFlow cache, aka a Tuple Space Explosion (TSE) attack.
