CVE-2026-36499  (opens in a new tab)

How to fix?

There is no fixed version for Echo:latest openvswitch.

NVD Description

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

A missing upper-bound check in the udpif_set_threads() function of Open vSwitch v3.6.90 allows an attacker with OVSDB write access to request an excessive number of handler or revalidation threads. This can cause a denial of service (DoS) via resource exhaustion.
