What to do
- Check whether you run it. Look for Kernel in your asset inventory, including appliances and cloud images. Stack check lists every exploited Linux CVE at once.
- Apply the fix. Apply updates per vendor instructions.
- If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 10 Nov 2016.
- Get told next time. Email alerts when CISA adds a CVE for Linux.
