What this list means
CISA adds a flaw to its Known Exploited Vulnerabilities catalog when there is reliable evidence that attackers have used it in the wild and clear steps exist to fix or reduce it. A listed flaw usually has a patch or workaround from the maker. Some older devices are no longer supported and will not be fixed. If you own an affected model, check the maker's notice, update the firmware or replace the device if it is out of support.
