# Security digest: August 21, 2024

4 known exploited (cisa kev) additions.

## Take stock

- Do you run any of these? Linux Kernel, Dahua IP Camera Firmware, Microsoft Exchange Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2024-09-11.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
