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 or discontinue use of the product if updates are unavailable.
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 8 Jan 2024.
Get told next time. Email alerts when CISA adds a CVE for Linux.
