What is the CISA KEV catalog?
Reviewed answer
The US agency CISA's KEV catalog lists security flaws known to have been exploited.
- Match the listed product and affected versions against what you actually use.
- Follow the maker's fix or temporary-protection instructions promptly if you are affected.
- Check the maker's notice even if a flaw is absent from KEV; absence does not establish safety.

An unpatched product you use matches an entry. The catalog indicates real exploitation, not proof that your own device was attacked.
